Novel mutations in PAX6, OTX2 and NDP in anophthalmia, microphthalmia and coloboma. 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. Martinez E, Madsen EC. SOX2 anophthalmia syndrome: 12 new cases demonstrating broader The term anophthalmia is often used . This syndrome causes a decrease in the production of sox2 protein which regulates the other gene's activities which bind to other regions of DNA. As a child enters the teen years, a transition plan should be discussed and incorporated in the IEP. Most cases result from new mutations in the SOX2 gene and occur in people with no history of the disorder in their family.

Kelberman D, de Castro SC, Huang S, Crolla JA, Palmer R, Gregory JW, Taylor D, Occasionally hypospadias is observed. It is also possible that complete failure of optic vesicle formation results in anophthalmia without optic nerve formation. Congenital anophthalmia is a developmental disorder in which the eye does not develop or is underdeveloped. Almost all SOX2 pathogenic variants reported to date appear to represent heterozygous loss of function; thus, it is difficult to draw genotype-phenotype correlations. Europe PMC is an archive of life sciences journal literature. SOX2 mutation causes anophthalmia, hearing loss, and brain anomalies. Expand All. In bilateral anophthalmia, both eyes are missing. The SOX2 phenotypes include a patient with anophthalmia, oesophageal abnormalities and horseshoe kidney, and a patient with a retinal dystrophy implicating SOX2 in retinal development.
