Special education law requires that children participating in an IEP be in the least restrictive environment feasible at school and included in general education as much as possible, when and where appropriate. OMIM; Schneider A, Young TL. sox2 anophthalmia syndrome life expectancy BACKGROUND: Developmental eye anomalies, which include anophthalmia (absent eye) or microphthalmia (small eye) are an important cause of severe visual impairment in infants and young children. F, Katowitz J, Schimmenti LA, Hummel M, Fitzpatrick DR, Young TL. It is so rare it occurs in one in 250,000 people. Make sure you get prenatal care (care before birth) early and consistently. The SOX2 protein regulates the activity of other genes, especially those that are important for normal development of the eyes. Less frequent variants, esp those that alter residues adjacent to Tyr160, are also assoc w/severe phenotype. An ocularist is a provider who can make prosthetic devices like artificial eyes and conformers. There are many ways to receive support: [3] Microphthalmia-associated transcription factor (MITF), located on chromosome 14q32, is associated with one form of isolated microphthalmia (MCOP1). 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. This process is controlled by specific transcription factors, such as the SRY-related HMG-box genes SOX2 and SOX21, that are activated or repressed through . In a small number of cases, people with SOX2 anophthalmia syndrome have inherited the altered gene from an unaffected parent who has a SOX2 mutation only in their sperm or egg cells.

Transmission of a constitutional loss-of-function pathogenic variant from a male proband to offspring has not been reported. We suggest that such deletions could be a relatively common cause of SOX2 anophthalmia syndrome and both tests should be included in the initial diagnostic . in the fellow eye. People can be born with one or two small eyes (microphthalmia) or without one or both eyes (anophthalmia). The medical team may not be aware of the multiple ways that a rare disease can change the quality of life of the patient and family. CMA is often used as a first step.
