OMIM Entries for SOX2 Disorder (View All in OMIM). 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. Note: The severity of disease and specific clinical findings vary and cannot be accurately predicted by the family history or results of molecular genetic testing. Once the causative genetic alteration has been identified in an affected family member (or a parent is known to have 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 variant. Its a specialized imaging test that may be helpful in evaluating for fetal congenital anomalies and associated complications.

Sox2 is involved in crystallin regulation in murine [ 22] and avian models [ 23] and humans, and SOX2 mutations cause microphthalmia and cataracts [ 24, 25 ]. Genes associated with ocular manifestations frequently observed in SOX2 disorder (with or without nonocular comorbidities) are summarized in Table 3.

Talk to your provider about the medications and over-the-counter products you take to make sure that they are compatible with a healthy pregnancy. The degree of visual impairment is usually severe and consistent with the degree of structural abnormality in the eye. The Human Phenotype Ontology (HPO) enables use of precise, standardized, computationally accessible terms to describe phenotypic abnormalities. Williamson KA, Yates TM, FitzPatrick DR.

Prosthetic eyes: Prosthetic eyes are placed in empty eye sockets. How do you know if your baby has anophthalmia or microphthalmia? The following descriptions are based on these key reports, together with all other published cases and the authors' unpublished data. Am J Med Genet A. Prostheses: Consider optically clear expanders to stimulate growth of the orbit & periorbital tissues. SOX2 is expressed in mouse embryonic stem cells and has been shown to act as part of a transcriptional activator complex for several important developmental genes including other genes known to be critical to eye development (e.g., PAX6 and MAF1). For example, even in extreme microphthalmia, functional retinal tissue can give some light/dark perception with or without color perception. 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 . While most centers would consider use of prenatal testing to be a personal decision, discussion of these issues may be helpful. Children may qualify for and benefit from interventions used in treatment of autism spectrum disorder, including applied behavior analysis (ABA). Microphthalmia and anophthalmia may happen along with other medical conditions that occur at birth, including issues with hands and feet malformation (like polydactyly), face and mouth malformation (like cleft lip and palate) and intellectual challenges. 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. They also help with socket and face development and can help with cosmetic concerns. SOX2 disorder, caused by an intragenic SOX2 pathogenic variant or a deletion of 3q26.33 involving SOX2, is an autosomal dominant disorder. 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 SOX2 protein regulates the activity of other genes, especially those that are important for normal development of the eyes. A 504 plan (Section 504: a US federal statute that prohibits discrimination based on disability) can be considered for those who require accommodations or modifications such as front-of-class seating, assistive technology devices, classroom scribes, extra time between classes, modified assignments, and enlarged text.
