Hagstrom SA et al: 20126410: 2010: SOX2 is an oncogene activated by recurrent 3q26.3 amplifications in human lung squamous cell carcinomas. Multiple pages were reviewed for this article. Both the globe (human eye) and the ocular True or primary anophthalmia is incompatible with life . While both eyes are usually affected in SOX2 anophthalmia syndrome, one eye may be more affected than the other. See Molecular Genetics for information on variants detected in this gene. SOX2 anophthalmia syndrome Luisa Sanctis 2005, American Journal of Medical Genetics Part A Microphthalmia (small eye), anophthalmia (absent eye), and coloboma (failure of optic fissure closure) (MAC) are commonly associated eye malformations with a combined birth incidence of about 2 per 10,000 . If CMA does not detect a copy number variant, genome sequencing and/or exome sequencing may be used. It has been called also the SOX 2 anophthalmia syndrome 3 due to the frequent mutations and/or deletions found in the SOX2 gene.

Gorman KM, Lynch SA, Schneider A, Grange DK, Williamson KA, FitzPatrick DR, King MD. ED. 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. Although normal eye development is possible in SOX2 disorder, all such individuals had extraocular defects. SOX2 (OMIM 184429) belongs to the SOX family of transcription factors that contain a 79-amino acid high mobility group (HMG) box DNA-binding domain similar to that found in the sex-determining gene SRY (OMIM 480000) (1, 2). Conformers: These are devices that fit into the eye socket to help your eye socket and face develop more typically. SOX2 disorder, caused by an intragenic SOX2 pathogenic variant or a deletion of 3q26.33 involving SOX2, is an autosomal dominant disorder. contact: ude.wu@tssamda. The term anophthalmia is often used . In bilateral anophthalmia, both eyes are missing. American Academy of Ophthalmology. 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.

To establish the extent of disease and needs in an individual diagnosed with SOX2 disorder, the evaluations summarized in Table 4 (if not performed as part of the evaluation that led to diagnosis) are recommended. [Google Scholar] 10. 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 that is intragenic or a deletion of 3q26.33 involving SOX2 (see Table 1). Surgery: You might need surgery to treat cataracts, coloboma or to help with the conformer fittings.

The features of this condition are present from birth. The incidence of parental germline mosaicism in. This may be an inappropriate acronym, as it implies that coloboma is an intrinsic part of all microphthalmia, which is not the case: coloboma has been reported but is not a common feature. Microphthalmia is a birth defect in which one or both eyes did not develop fully, so they are small.
