GeneReviews is not responsible for the information provided by other As SOX2 is a single-exon gene, there are no alternative splice transcripts and it is not subject to nonsense-mediated decay; however, loss-of-function variants have been observed throughout the exon. Standards and guidelines for the interpretation of sequence variants: a joint consensus recommendation of the American College of Medical Genetics and Genomics and the Association for Molecular Pathology.

An ophthalmologist is a medical doctor who is trained in diagnosing and treating eye conditions and vision conditions. 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.
