Information on exact seizure type is limited, but most appeared to be grand mal tonic-clonic seizures that appeared in early childhood and responded well to standard anticonvulsant medication. For more information, see the GeneReviews Copyright Notice and Usage Microcornea: A microcornea is a cornea thats very small. It is also possible that complete failure of optic vesicle formation results in anophthalmia without optic nerve formation. Once the causative genetic alteration has been identified in an affected family member (or in a parent who has a structural chromosome rearrangement involving the 3q26.33 region), prenatal testing for a pregnancy at increased risk is possible, and preimplantation genetic testing for SOX2 disorder may be possible, depending on the specific familial genetic alteration.

People with SOX2 anophthalmia syndrome are usually born without eyeballs (anophthalmia), although some individuals have small eyes (microphthalmia). Some affected individuals have inherited the genetic alteration from either an affected mother (transmission from an affected father to child has not been reported to date) or an unaffected parent with germline mosaicism.

The majority of affected individuals have some evidence of hypothalamic-pituitary axis dysfunction when detailed measurement of growth hormone and gonadotropins is undertaken [Tziaferi et al 2008]. If a parent has a balanced structural chromosome rearrangement involving the 3q26.33 region, the risk to sibs is increased.

Hum Mol Genet. Note: Note: Per ACMG/AMP variant interpretation guidelines, the terms "pathogenic variants" and "likely pathogenic variants" are synonymous in a clinical setting, meaning that both are considered diagnostic and both can be used for clinical decision making [Richards et al 2015]. Tziaferi V, Kelberman D, Dattani MT. Mol Vis. Microphthalmia - Wikipedia Variants may include small intragenic deletions/insertions and missense, nonsense, and splice site variants; typically, whole-exon or whole-gene deletions/duplications are not detected. With the current widespread use of advanced molecular genetic testing, it is apparent that the clinical spectrum associated with SOX2 pathogenic variants includes anophthalmia and/or microphthalmia as well as phenotypes with minimal or absent ocular findings. The majority of SOX2 mutations identified appear to arise de novo in probands ascertained through the presence of anophthalmia or microphthalmia.
