Anophthalmia-esophageal atresia syndrome caused by an SOX2 gene deletion in monozygotic twin brothers with markedly discordant phenotypes. It is also possible that complete failure of optic vesicle formation results in anophthalmia without optic nerve formation. 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 . Your provider will be able to tell if your baby has microphthalmia or anophthalmia by looking carefully during a physical examination and doing an eye exam. 8 color. Abnormal development of these structures causes the signs and symptoms of SOX2 anophthalmia syndrome. 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.

Frequency refers to the number of times the term was used in all included case reports. Approximately 60% of affected individuals have a de novo genetic alteration. SOX2 anophthalmia syndrome Clinical Information Anophthalmos-. congenital absence of the eye or eyes. 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). Two or more of these features need to be present for a clinical diagnosis only 30% of patients have all three. GARD: 19 Anophthalmia plus syndrome (APS) is a very rare syndrome that involves malformations in multiple organs of the body.
