It encompasses all individuals with a SOX2 pathogenic variant who should be evaluated for medically actionable manifestations across the entire phenotypic spectrum (regardless of clinical findings that prompted molecular genetic testing). In the US, developmental preschool through the local public school district is recommended. It has been called also the SOX 2 anophthalmia syndrome 3 due to the frequent mutations and/or deletions found in the SOX2 gene. Approximately 2/3 of all cases of anophthalmia are determined to be of genetic basis. People can be born with one or two small eyes (microphthalmia) or without one or both eyes (anophthalmia).

Some people with this condition are born with a blocked esophagus (esophageal atresia), which is often accompanied by an abnormal connection between the esophagus and the trachea (tracheoesophageal fistula). Without this Sox2 protein, the activity of genes that is important for the development of the eye is disrupted. As these features can be present in children without severe structural eye defects [Zenteno et al 2006, Dennert et al 2017], they are not restricted to individuals with the full AEG syndrome [Williamson et al 2006].

Services to help a child and their family deal with vision loss or blindness. The diagnosis of SOX2 disorder is established in a proband in whom molecular genetic testing identifies either a heterozygous intragenic SOX2 pathogenic (or likely pathogenic) variant or a deletion of 3q26.33 involving SOX2. Individuals with the distinctive findings described in Suggestive Findings are likely to be diagnosed using gene-targeted testing that could include CMA (see Option 1), whereas those in whom the diagnosis of SOX2 disorder has not been considered or previously made by CMA may be diagnosed using comprehensive genomic testing (see Option 2). Specific recommendations regarding type of therapy can be made by a developmental pediatrician. In . Microphthalmia is a birth defect in which one or both eyes did not develop fully, so they are small. In females, malformations are less frequent and can include hypoplastic or hemi-uterus, ovary or vaginal agenesis, and vaginal adhesions [Errichiello et al 2018]. It is also possible that complete failure of optic vesicle formation results in anophthalmia without optic nerve formation. This gene provides instructions for making a protein that plays a critical role in the formation of many different tissues and organs during embryonic development. DDA is a US public agency that provides services and support to qualified individuals. The SOX2-associated ocular malformations are variable in . Some babies are born with these conditions due to genetic changes. The most common genetic cause for anophthalmia is mutated SOX2gene. genomic testing (CMA, exome sequencing, exome array, genome sequencing) depending on the phenotype. Molecular genetic testing approaches can include a combination of gene-targeted testing (single-gene testing, multigene panel, and chromosomal microarray analysis [CMA]) and comprehensive Ted has Sox2 anophthalmia syndrome, caused by an unbalanced translocation of Chromosomes 3 and 14 and a microdeletion of Chromosome 3.

Measurement of weight, length/height, & head circumference, Complete ophthalmologic exam by experienced pediatric ophthalmologist, Males: Assessment for micropenis &/or cryptorchidism. Once the causative genetic alteration has been identified in an affected family member (or in a parent who has 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 genetic alteration. Edinburgh, United Kingdom, Consultant in Pediatric Genetics, MRC Human Genetics Unit The eyes are often absent or severely underdeveloped (anophthalmia), or they may be abnormally small (microphthalmia). Microphthalmia means that one eye or both eyes dont develop fully so they are small and disorganized. The most common findings in affected individuals are anophthalmia (absence of one or both eyes) or severe microphthalmia (abnormally small eyes), and cleft lip and/or cleft palate. Sox2 anophthalmia syndromeis caused by a mutation in the Sox2 gene that does not allow it to produce the Sox2 protein that regulates the activity of other genes by binding to certain regions of DNA.

Its a good idea to have all these members of your healthcare team (or your childs team), along with experts who can help with any other areas of need. Sex Dev. One of the genetic causes for Anophthalmia is the sox2 gene. [ Read summary ] Many factors can affect how long a person with Down syndrome lives. It is not yet clear which of these spectra are associated with SOX2 eye disorders, as most affected individuals have very small or absent eyes, which are thus morphologically unclassifiable. For those receiving IEP services, the public school district is required to provide services until age 21. OMIM; For issues to consider in interpretation of sequence analysis results, click here.

Delayed motor development was reported in the majority of affected children; the age of achieving independent walking ranged from 12 months to four years, although some individuals never achieve independent ambulation. Here we provide a detailed description of the clinical features associated with SOX2 mutations in the five individuals with reported mutations and four newly identified cases (including the first reported SOX2 missense mutation). You must talk to your provider if you take isotretinoin and thalidomide. The Human Phenotype Ontology (HPO) enables use of precise, standardized, computationally accessible terms to describe phenotypic abnormalities. For questions regarding permissions or whether a specified use is allowed, Posted on June 7, 2022 by Seattle (WA): University of Washington, Seattle; 1993-2023. 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.
