Note the brown discoloration of the muscular layer. ). indications - age 3-8 years (younger is difficult to get good anchor purchase), in situ arthrodesis, anterior/posterior or posterior alone, unilateral unsegmented bars with minimal deformity, intact growth plates on the concave side of the deformity, patients less than 5 yrs. Nondividing cells in G0 may also reenter the cell cycle. These bones help protect your spinal cord from injury while allowing you to twist and turn. This permeabilization of the outer mitochondrial membrane releases cytochrome c from the intermembrane space into the cytosol. Oncotic cell death results from irreversible cell injury that, for example, is caused by hypoxia, ischemia, or direct damage to cell membranes (Essential Concept 1-3 Methemoglobinemia, Experimental Nitrite Poisoning, Hind Quarters, Pig. However, like the cervical vertebrae, they have atriangular-shaped vertebral foramen. 1-20) and proposes that endogenous and exogenous factors contribute to telomere dysfunction, impaired DDR, or increased ROS, each of which can independently activate p53, which in turn compromises mitochondrial function through repression of coactivators of peroxisome proliferator-activated receptor (PPAR), a nuclear receptor that regulates many metabolic pathways. Their significance, other than as a marker of aging, is unknown. For example, chromosome 1q21.1 refers to band 21.1 on the long arm of chromosome 1. However, rare cases of ARCS and MRKH in the same family have been reported, making both syndromes likely to be of identical genetic origin. In: Parvizi J, Ed. Right, Normal control. Your thoracic spine has several important functions, including: The three sections of your spine form three natural curves. Canine distemper virus produces both cytoplasmic and intranuclear inclusions (see Fig. The effects of mutations can be considerable if not repaired by one of these mechanisms. Philadelphia, PA. 2003:695. *Data, in part, from Guide to congenital and heritable disorders in dogs, Davis, CA, May 2011, The Humane Society Veterinary Medical Association. This allele may come from the sire or from the dam; thus, if one parent carries even one mutated allele (heterozygous), each offspring has a 50% chance of inheriting the mutation. Females who undergo surgery to create an artificial vagina will most likely need to use vaginal dilators after the surgery to enhance the chance of success. With this method, a physician (and then woman herself) applies a vaginal dilator, which progressively stretches and widens the vagina. Conversely, cells that are no longer necessary or that no longer receive the stimulus of physical exercise, innervation, hormones, or growth factors tend to shrink as in the disuse atrophy or denervation atrophy in skeletal muscles or the physiologic atrophy of the mammary gland after weaning of the offspring. In other cases, KFS may be inherited as an autosomal dominant or autosomal recessive trait. Ionizing radiation, with its frequencies above the ultraviolet range, ionizes atoms or molecules, which then cause direct cell membrane or organelle damage or the production of free radicals that react with other cellular components, especially DNA. General pathology is the study of the reaction of cells or tissues to injury with a focus on the mechanisms of that response. Icterus is often classified pathogenetically as prehepatic, hepatic, or posthepatic (see Chapter 8). Examination reveals mild scoliosis and a large hairy patch on the childs back. Depending on the dose and duration of exposure and other factors, CCl4 toxicosis causes a variety of lesions via membrane injury, including steatosis (fatty liver), apoptosis and regeneration of hepatocytes, and hepatic necrosis with fibrosis. Among the congenital vertebral anomalies, hemivertebrae are the most likely to cause neurologic problems. Surgical pathology (histologic examination of surgically excised tissue specimens) not only facilitates diagnosis and prognosis for a living animal but also can be the basis for therapy. Free ribosomes are located in the cytosol and are able to move throughout the cell, whereas fixed ribosomes are attached to the rER. Each chromosome has a short arm designated p and a long arm designated q. Another pathway of regulated necrosis is initiated by opening of the MPT pore, which entails an increase in permeability of inner and outer mitochondrial membranes and leads to mitochondrial swelling, production of ROS, and oxidized nicotinamide adenine dinucleotide (NAD+) depletion. Cell death typically assumes one of two morphologic forms (Fig. 1-3 Grossly, coagulative necrosis appears pale tan to pale gray, often sharply demarcated from the normal color of adjacent viable tissue, and solid (without apparent crumbling, sloughing, liquefaction, or other obvious loss of structure). Skeletal muscle is not so quick to autolyze but retains the ability to contract after somatic death, especially when immersed in formalin, so muscle biopsy specimens must be clamped in a slightly stretched state before fixation to avoid contraction artifacts. MUllerian duct aplasia-Renal dysplasia-Cervical Somite anomalies Assoc. At low concentrations, opening of the MPT pore can induce protective autophagy to remove dysfunctional mitochondria. Finally, soluble NSF (N-ethylmaleimidesensitive fusion protein) attachment protein receptor (SNARE)like proteins are involved in docking and fusion of the lysosome to the autophagosome. Cell walls are disrupted, and tissue architecture is lost. The mutation causes abnormal lysosomal structure and function in leukocytes and in melanocytes. This type of kyphosis is more rigid and can worsen with growth. The superior and inferior aspects of the vertebral body are lined with hyaline cartilage. In: Damjanov I, Linder J, editors. 14-87). Researchers have determined that some cases of KFS are associated with mutations of the GDF6 gene on chromosome 8. There are hundreds of different types of glycoprotein and lipoprotein transmembrane receptors; each type is linked to a specific intracellular biochemical pathway, and individual cells contain many of these receptors based on their function as determined by their genome. Arterial thrombosis (e.g., saddle thrombus formation at the iliac bifurcation of the aorta in cats) and frostbite are causes of dry gangrene of extremities. Bethesda, MD 20894, Web Policies 14-63 and 14-64), glycogen storage diseases (see Fig. Zachary, College of Veterinary Medicine, University of Illinois. A renal ultrasound should be obtained in a patient with which of the following diagnoses? Dead cells also tend to have intense cytoplasmic eosinophilia because of the denatured protein and loss of ribosomes, hence loss of basophilia. Arrest of the cell cycle can be a temporary pause for DNA repair or can progress to senescence (an irreversible growth arrest) or to cell death through apoptosis. ; see also Figs. A diagnosis is made based upon identification of characteristic symptoms, a detailed patient history, a thorough clinical evaluation and a variety of specialized tests such as specialized imaging techniques. Traumatic Spondylolisthesis of Axis (Hangman's Fracture), Cervical Lateral Mass Fracture Separation, Extension Teardrop Fracture Cervical Spine, Clay-shoveler Fracture (Cervical Spinous Process FX), Chance Fracture (flexion-distraction injury), Osteoporotic Vertebral Compression Fracture, Ossification Posterior Longitudinal Ligament, DISH (Diffuse Idiopathic Skeletal Hyperostosis), Atlantoaxial Rotatory Displacement (AARD), Pediatric Intervertebral Disc Calcification, Pediatric Spondylolysis & Spondylolisthesis. The biologic significance of meiosis and mitosis lies in ensuring the constancy of chromosome number and thus the integrity of the genome from one cell to its progeny and from one generation to the next. Congenital means a condition you are born with. ), (Courtesy Dr. W. Crowell, College of Veterinary Medicine, The University of Georgia; and Noah's Arkive, College of Veterinary Medicine, The University of Georgia. Maillet M, van Berlo JH, Molkentin JD. B, Congophilic substances, such as amyloid, are red-orange with Congo red stain. Psychological distress in women with uterovaginal agenesis (Mayer-Rokitansky-Kster-Hauser syndrome, MRKH). Cytochrome c promotes the assembly of the caspase-activating complex or apoptosome, which consists of caspase-9 plus apoptotic protease activating factor 1 (Apaf-1). 2, Missense mutations. Some SASP factors promote or inhibit proliferation depending on the setting. Kalogeris T, Baines CP, Krenz M. Cell biology of ischemia/reperfusion injury. The abnormal gene can be inherited from either parent, or can be the result of a new mutation (gene change) in the affected individual. Thus an important consideration in genetic diseases is the period during which a normal gene would be active. ; see also Chapter 3). But excessive curvature can affect posture and make standing difficult. The ultimate effect on the animal depends on the number of cells affected, reparative and regenerative abilities of the cell, and the importance of the disrupted biochemical processes, such as ATP synthesis. Study of the cell cycle is fundamental to understanding development, homeostasis, and cellular proliferation in response to physiologic or pathologic stimuli, genetic disease, and the effects of cellular aging that include both the uncontrolled cellular proliferation of neoplasia and the permanent cessation of cellular replication known as senescence. Scheuermanns kyphosis with a curve of more than 75 degrees. Hepatic icterus is the result of hepatocellular injury that decreases the uptake, conjugation, or secretion of bilirubin. Spinal tumors are more likely to develop in this area of your spine. Oxyhemoglobin, formed when oxygen binds to the heme group, gives oxygenated (arterial) blood its red color and imparts a pink tinge to well-perfused and well-oxygenated tissues. Such mutations can affect protein synthesis by disrupting one or more steps in transcription or translation and lead to the following: Types of Base-Pair Substitutions in Gene Mutations. The primary defect is an imbalance in calcium and phosphate concentrations in the blood. In contrast, the cell that dies by apoptosis shrinks and fragments, but the fragments remain membrane bound and therefore do not elicit an inflammatory response although they are marked for phagocytosis. In the CNS the cell swelling of cytotoxic edema has little effect on the color of neuroparenchyma but does increase the weight and volume of the affected tissue. The slice on the right has green discoloration caused by leakage of bile into the surrounding parenchyma after death (bile imbibition). The initial response of the cell to perturbation of homeostasis is acute cell swelling. For example, a poorly differentiated mast cell tumor might necessitate histochemistry, immunohistochemistry, or perhaps even molecular diagnostics, such as PCR amplification of nucleic acids, whereas the H&E histologic section may suffice for a well-differentiated mast cell tumor. In immunohistochemistry, an immune reaction (binding of antibody to an antigen) is combined with histochemistry for more specific identification of microbes in the case of infectious disease or of cellular antigens in neoplastic or noninfectious diseases. The joints between the articular facets, called facet joints, allow for some gliding motions between the vertebrae. As examples, neurons, cardiac myocytes, endothelium, and epithelium of the proximal tubule of the kidney are cells that are extremely susceptible to hypoxia, whereas fibroblasts, adipocytes, and other mesenchymal structural cells are less susceptible. However, ferritin, a globular iron storage protein present in all tissues and particularly in the liver, spleen, and bone marrow, binds free iron and stores it in a nontoxic form available for use by the cell. Thus, with a codon of three nucleotides, there are 64 possible triplet combinations that constitute the genetic code and the basis for synthesis and assembly of proteins. This narrows the space between your vertebrae, causing certain issues. Pseudomelanosis is a blue-green to black discoloration of tissues, especially along the digestive tract, by iron sulfide depositsthere is no melanin in pseudomelanosisthat are formed by the reaction of hydrogen sulfide from putrefactive bacteria with the iron in hemoglobin from lysed erythrocytes. Individual proteins in a proteome do not function in isolation. Heterozygotes, with only one mutated allele, are clinically normal carriers of the trait. Nonsurgical techniques are considered the first-line approach. The history of pathology: an overview. Injured cells can accumulate endogenous by-products and exogenous substances because of metabolic abnormalities, genetic mutations, or exposure to an indigestible exogenous substance. 1-56 Injury, such as that caused by viruses or endotoxin, to endothelial cells, basement membrane, or smooth muscle cells of the tunica media can activate the acute phase inflammatory response leading to circumferential deposition of plasma proteins in blood vessel walls. ), Disruption of biochemical pathways, especially those of protein synthesis, (Courtesy Dr. D.E. Tension Myositis Syndrome Single-gene disorders arise from a mutation in one gene and result in a permanent change of the cell's nuclear DNA (E-Figs. It appears that the initial injury or the subsequent cellular acidosis denatures not only structural proteins, but also lysosomal enzymes in the affected cell. B, Acute hemolytic anemia, babesiosis, liver, cow. The answer to this conundrum is found in two features of genes. mRNA, Messenger RNA; tRNA, transfer RNA. Deoxygenated hemoglobin explains the blue cast to venous blood and accounts for the blue to purple discoloration, known as cyanosis (Fig. ). Tightly coiled chromatin is called heterochromatin and is clumped around the inner nuclear membrane and is inactive (see also E-Fig. 8-38). Other histochemical techniques are used to identify substances (e.g., mucins, glycogen, amyloid) that are either not differentially stained by H&E or are stained only weakly. There is no biological hyperandrogenism, as shown by a normal plasmatic level of testosterone. official website and that any information you provide is encrypted Scoliosis Nitrite poisoning can be associated with consumption of nitrate-accumulating plants by livestock, usually ruminants, or from a water source contaminated with nitrate runoff from fertilized fields. Most people with kyphosis who get diagnosed early dont need surgery and have typical function. Localized postmortem bacterial proliferation in the liver can result in spots of pallor that resemble necrotic foci. Macroscopically, caseation may appear as crumbled, granular, or laminated yellow-white exudate in the center of a granuloma or a chronic abscess. Twelve vertebrae, numbered T1 through T12 from top to bottom, make up the thoracic spine. Vertebral wedging is a general term used to describe spinal bones which demonstrate an atypical shape, similar to that of a wedge. Honest and understandable information about back pain since 2006. Nicholas FW. Free radicals damage cell lipids (especially the phospholipids of cell membranes), proteins, and nucleic acids (Fig. Lysosomes are membrane-bound vesicles (see Fig. MD: The Johns Hopkins University; Entry No:601076; Last Update: 07/22/2011. The intervertebraldisc is afibrocartilaginouscylinder that lies between the vertebrae, joining them together. Unlike most other spinal vertebrae, the atlas does not have a vertebral body. The initiator caspases that start the process of apoptosis include caspase-8 (activated by the death-inducing signaling complex (DISC) of the extrinsic pathway), caspase-9 (activated with the apoptosome in the intrinsic pathway), and caspase-2 (activated by p53 following DNA damage). Cestrum diurnum, a plant introduced from the West Indies to the Gulf Coast of the United States, is poisonous to herbivores because it contains glycosides of 1,25-dihydroxycholecalciferol (1,25-(OH)2D3) that cause elevated serum calcium concentration and often severe metastatic calcification of the lungs, kidney, and heart, especially the atrial endocardium and ascending aorta. The viral inclusions of rabies, called Negri bodies, are in the cytoplasm of neuronal soma. The disease can be differentiated from gout by chemical analysis of the crystalline deposits. Note that one of the claws (left) has been lost due to the process. 1-4) and internally in organs and tissues of the down side. If a mutated gene is expressed during the active period for the normal gene, the outcome may be detrimental. Your back has many interconnected bones, nerves, muscles, ligaments and tendons that protect your spinal cord. Inflammatory mediators produced by these macrophages induce interstitial fibrosis, which caused the failure of the lungs to collapse upon opening of the thoracic cavity. The rupture usually occurs in a posterior-lateral direction, after which the nucleus pulposis can irritate nearby spinal nerves resulting in a variety of neurological and muscular symptoms. Calcification, Vitamin E or Selenium Deficiency, Heart, Lamb. Boys have Scheuermanns kyphosis about twice as ofen as girls do. Notably, the cardiac glycosides, digitalis and ouabain, specifically inhibit Na+/K+-ATPase pumps. The Normally adipocytes are present in small numbers in the myocardial interstitium, especially near the epicardium, and in skeletal muscle bundles. GSH, Reduced glutathione; GSSG, oxidized glutathione; SOD, superoxide dismutase. 1-20, A Such materials can be caustic in their own right and are also likely to deliver bacteria from the environment or oropharynx into the lung. If we don't have a program for you now, please continue to check back with us. Increasingly diseases are recognized to be the result of misfolding of soluble and functional peptides or proteins, converting them into relatively insoluble and nonfunctional aggregates. The student should remember that the morphologic appearance of necrotic cells and tissues changes with time. peripheral pulmonic stenosis, cholestasis, facial dysmorphism Wedge vertebra. Hyaline accumulations may also be a normal finding in specific types of cells (e.g., the globular Russell bodies [immunoglobulin-containing protein in distended rER] of plasma cells). Severe or persistent injury can overwhelm the cell's capacity to restore homeostasis, in which case potentially reversible acute cell swelling can become irreversible and progress to cell death. The calcium imbalance exacerbates the damage to mitochondria and to the cytoskeleton and activates endonucleases, proteases, and phospholipases. This essay profiles hemivertebra conditions in the backbone and their potential effects on the form and function of the spine. Hyperplasia implies an increase in number of the principal cells of a tissue or organ (see Fig. Separation of S1 from the sacrum is termed "lumbarisation", while fusion of L5 to the sacrum is termed "sacralisation". Pig livers at various intervals after death. Melanin is formed in organelles called melanosomes, then transferred through dendritic cell processes to adjacent keratinocytes. A radiograph was obtained demonstrating a non-flexible 40-degree curve with multiple vertebral anomalies, highlighted by a convex segmented hemivertebra associated with a concave unilateral bar. The following disorders may be associated with MRKH syndrome type II as secondary characteristics. Atrophy is the decrease in the mass of a tissue or organ due to decreased size and/or number of cells after it has reached its normal size (see Fig. or consume (e.g., Haemonchus contortus) erythrocytes liberate heme during the proteolysis of hemoglobin. Heller-Boersma JG, Schmidt UH, Edmonds DK. The causes of cellular or tissue atrophy include nutrient deprivation or loss of hormonal stimulation, decreased workload (disuse atrophy), denervation (especially in skeletal muscles), and compression (e.g., adjacent to neoplasms, other masses, or distended body cavities). The cell cycle is controlled by a family of cyclin-dependent kinases (CDKs) that are activated by cyclins. Simplistically, hematoxylin stains nuclei and certain cytoplasmic structures, such as ribosomes, that contain nucleic acids, whereas eosin stains proteins, both cytoplasmic and extracellular (e.g., collagen). 1-21 Lysosomal storage diseases are characterized by a deficiency of lysosomal acid hydrolases with incomplete breakdown of their substrates, leading to accumulation of the partially degraded insoluble metabolite within lysosomes (E-Fig. A, Hepatic swelling in a mouse exposed to chloroform 24 hours previously. 1-54, B). 1-38 The appearance of necrotic cells depends on the type of necrosis (see the next section), the tissue involved, the cause of cell death, and the time elapsed. The three most common types of kyphosis are postural kyphosis, Scheuermanns kyphosis and congenital kyphosis. Knowledge of anatomy and of normal anatomic variations is prerequisite to lesion recognition and interpretation. Mitotic nondisjunctions can also be inherited. Specific diseases with genetic bases are discussed in more detail in the Pathology of Organ Systems chapters; this section provides an E-content overview of (1) the structure and function of chromosomes and genes, (2) some basic mechanisms of genetic disorders, and (3) the outcomes of specific genetic diseases and includes: The interaction of microbial genes with host genes in determining resistance to infectious diseases is discussed in Chapter 4. Ballooning Degeneration, Papular Stomatitis, Oral Mucosa, Ox. Complement component 6 (C6) binds a labile site on C5b to produce a stable intermediate. The fibrinoid change is accompanied by leukocytic infiltration and medial necrosis. The severity of MRKH syndrome type I may vary greatly from one person to another. Caspase-8 can also truncate Bid, a proapoptotic Bcl-2 protein, which translocates to mitochondria to trigger intrinsic apoptosis (see the next section). Liquefaction progresses with arrival of macrophages (gitter cells) to phagocytize the myelin debris and other components of the necrotic tissue. The exact cause of MRKH syndrome remains largely unknown but ongoing research has begun to provide some clues to its mechanism. Kyphosis occurs when the vertebrae in the back become more wedge shaped. Cells infected by certain poxviruses (e.g., papular stomatitis virus) cannot regulate their volume and undergo hydropic degeneration at certain stages of the infection. 14-63) and mucopolysaccharidoses, and aminoacidopathies that affect organs such as the brain, spinal cord, skeletal muscle, liver, and kidney. Postmortem changes are the result of autolysis (postmortem decomposition) rather than of some pathologic process; thus they are not lesions. 1-41, A Mitosis is somatic cell division by which the body grows and differentiates and tissues regenerate. It causes a hunchback look and can make you feel self-conscious. Therein, genetic diseases of the skin are organized by species, diagnoses, and mechanisms. In some cases, the Fallopian tubes may be affected as well. Mitochondria have a biochemically distinct inner and outer membrane. ). However, many of the common aging lesions in geriatric animals (e.g., nodular hyperplasia in the liver [see Fig. Since January 2020 Elsevier has created a COVID-19 resource centre with free information in English and Mandarin on the novel coronavirus COVID-19. Since the discovery that functional telomeres were the limiting factor for replication of fibroblasts in cell culture, telomeres have been at the forefront of research on cellular aging. They permit theflexibilityof the spine, and act as shock absorbers. Melanin deposits are subpleural and extend into pulmonary parenchyma. 1-35, A 1-14 Most chromosomal disorders are caused by errors in cell division, which transfers the disorder within somatic and/or germline cells. The yellow discoloration from the bilirubin is particularly evident in fat and mesentery. Figure A demonstates different anatomic patterns in congenital scoliosis. 1-46 The second messenger initiates an intracellular signal transduction cascade that stimulates or alters a metabolic pathway. Treatment may require the coordinated efforts of a team of specialists. A, Glycogen, accumulated in the cytoplasm of hepatocytes, appears as magenta granules with the periodic acidSchiff technique. The cytosol is electron lucent, mitochondria are swollen, and cisternae of the ER and Golgi complex are dilated. But most people with kyphosis do not need surgery. Cell membranes can also be selectively injured by chemical modification of their phospholipids by free radicals (i.e., lipid peroxidation), by covalent binding of toxins to macromolecules, by interference with ion channels, and by insertion of transmembrane complexes. 1-17). Not surprisingly, mitochondria, which are perhaps the organelles most susceptible to injury, are also thought to direct many of the processes of cellular adaptation, degeneration, and death through apoptosis or programmed necrosis (Fig. The chalky white lesions are areas of myocardial necrosis that have been calcified. Cell surface receptors are central to the pathogenesis of many disorders discussed throughout this book. In some cases, the findings are part of normal spinal arthritic processes and are minor and inconsequential. The ER and the rest of the cytocavitary network swell and fragment into vesicles. However, for a gene to be active, the condensed DNA must revert to long strands of DNA for transcription into RNA. A, Note the uniformly pale yellow-tan color. Some women may also experience pain during intercourse. Exceptions to this are C1 (no spinous process) and C7 (spinous process is longer than that of C2-C6 and may not bifurcate). Soft tissue calcification as the result of elevated serum calcium concentration is termed metastatic calcification, whereas the calcification of dead tissue as part of the process of necrosis is called dystrophic calcification. The causes of hepatic lipidosis (Fig. Ligand-receptor interactions play key roles in these functions. Take steps to stay healthy and strong. The display of colorsred, yellow, and brownis due to hemoglobin, bilirubin, and hemosiderin, respectively, from the breakdown of the erythrocytes. Back Muscle Pain Neurons are generally the cells most susceptible to necrosis, especially from hypoxia or ischemia, and develop (early in the process of cell death) the morphologic features of coagulative necrosis. Ionizing radiation injury is a localized side effect of radiation therapy for cancer. MD: The Johns Hopkins University; Entry No:277000; Last Update: 04/08/2014. Senescent cells (i.e., cells that were mitotic but have ceased to divide because of accumulated DNA damage or other factors) have cytologically detectable heterochromatin foci, increased volume, and a flattened profile if adherent to a basement membrane or other scaffolding. ), (Courtesy Dr. M.D. Corynebacterium pseudotuberculosis, the cause of caseous lymphadenitis in sheep and goats, is another bacterium that can replicate in phagosomes of macrophages without being destroyed by lysosomal enzymes. The resultant electrochemical gradient generates energy that is especially important in establishing and maintaining the membrane potential of neurons and of cardiac and skeletal muscle cells and pH homeostasis within the cytosol of the cell. This results in reddening of tissues that can be observed externally in pale-skinned, sparsely haired animals (E-Fig. Other tissues, such as smooth muscle, bone, and cartilage, are intermediate in their ability to proliferate. Has a flexible curve changing position changes the curvature. In addition, in some cases, neurological complications may result due to associated spinal cord injury. B, Note the squamous metaplasia of the esophageal glands. The cytoplasm of proximal tubular epithelial cells is filled with eosinophilic dropletsprotein that has been resorbed by the cells from the glomerular filtrate. Facet Joint Syndrome These nerves branch off of your spinal cord and supply sensation (feeling) and movement to certain areas of your body. Orphanet J Rare Dis. 1-20, B Access over 1700 multiple choice questions. In these cases, hematin can be removed by soaking the dewaxed tissue section before H&E staining in a saturated alcoholic solution of picric acid. Hematogenous pigments are derived from erythrocytes. 11-34), liver (especially the space of Disse; see Chapter 8 and Fig. Consequently, the sinusoids are wider. Telomerase consists of an RNA subunit template component (TERC) and a catalytic component (TERT), which is a reverse transcriptase. Research is ongoing to determine the exact underlying causes of MRKH syndrome including identifying the gene or gene(s) involved in the development of the disorder and whether environmental factors play a role.
