sox2 anophthalmia syndrome life expectancy

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. Anophthalmia means that one or both eyes dont develop at all so they are missing. 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. Bilateral anophthalmia and/or microphthalmia, Unilateral anophthalmia or microphthalmia, Genital abnormalities. 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). SOX2 anophthalmia syndrome is estimated to affect 1 in 250,000 individuals. Novel SOX2 mutation in autosomal dominant cataract-microcornea syndrome However, there are treatments that include: Theres no way to completely eliminate your risk of microphthalmia and anophthalmia, but there are ways to make pregnancy safer: Theres no cure for microphthalmia or anophthalmia. Bean LJH, Gripp KW, Amemiya A, editors. The role of SOX2 in hypogonadotropic hypogonadism. Individuals with SOX2 anophthalmia syndrome may also have seizures, brain abnormalities, slow growth, delayed development of motor skills (such as walking), and mild to severe learning disabilities. For more information, see the GeneReviews Copyright Notice and Usage A minority of affected individuals develop early continual dystonic posturing that is similar to that seen in dystonic cerebral palsy but without evidence of basal ganglia injury on neuroimaging.

The following information represents typical management recommendations for individuals with developmental delay/ intellectual disability in the United States; standard recommendations may vary from country to country. 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. They may also. Mutations in the SOX2 gene prevent the production of functional SOX2 protein. SOX2 @ The Human Genetics Unit Edinburgh U.K. Gene-targeted deletion/duplication analysis, ~24% (~21% that could also be resolved by CMA & ~3% that are below the limit of detection by CMA), Bilateral microphthalmia &/or anophthalmia, Bilateral anophthalmia, optic disc aplasia/hypoplasia, Bilateral microphthalmia, coloboma, cataract, Unilateral or bilateral microphthalmia &/or anophthalmia. HPO terms that appear fewer than four times were excluded. 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. People with SOX2 anophthalmia syndrome are usually born without eyeballs (anophthalmia), although some individuals have small eyes (microphthalmia).
