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. While both eyes are usually affected in SOX2 anophthalmia syndrome, one eye may be more affected than the other. Approximately 60% of affected individuals have a de novo genetic alteration. In general, retina tissue that is present has some functional activity. When anophthalmia or microphthalmia is the only condition a baby has, it's called nonsyndromic or isolated.

SOX2 encodes the transcription factor SOX2 (317 amino acids) which has an HMG DNA-binding domain (amino acids 40-111), a partner-binding region, and a C-terminal transactivation region. The term anophthalmia is often used interchangeably with severe microphthalmia because individuals with no visible eyeballs typically have some remaining eye tissue. If the genetic alteration identified in the proband is not identified in either parent, the following possibilities should be considered: The proband inherited a pathogenic variant from a parent with germline mosaicism. National Library of Medicine. Note on Table A, Locus-Specific Databases: See also the DECIPHER database. Without this Sox2 protein, the activity of genes that is important for the development of the eye is disrupted. Advertising on our site helps support our mission.
