Additionally, feeding difficulty or gastroesophageal reflux was observed in multiple individuals. The optimal time for determination of genetic risk and discussion of the availability of prenatal/preimplantation genetic testing is before pregnancy. 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. SOX2 anophthalmia syndrome. For more information, see the GeneReviews Copyright Notice and Usage Disclaimer. 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).

This condition is caused by an extra X chromosome in each of a female's cells. Triple X syndrome. Status dystonicus (a movement disorder emergency in which there is prolonged, generalized, intense, and painful muscle contraction) was originally reported in individuals with bilateral anophthalmia and a specific variant (see Genotype-Phenotype Correlations and Table 7) [Gorman et al 2016]; however, other variants, including the most common SOX2 variant, were subsequently associated with this feature in two individuals with bilateral anophthalmia or bilateral optic disc abnormality [Martinez & Madsen 2019, Pilz et al 2019]. 2007 Nov .

Recommended Evaluations Following Initial Diagnosis in Individuals with SOX2 Disorder, Treatment of Manifestations in Individuals with SOX2 Disorder. Genital anomalies are present in only 33% of reported AEG. The absence of the eye will cause a small bony orbit, a constricted mucosal socket, short eyelids, reduced palpebral fissure About 10 percent to 15 percent of people with anophthalmia in both eyes have SOX2 anophthalmia syndrome.

People can be born with one or two small eyes (microphthalmia) or without one or both eyes (anophthalmia). It is also possible that complete failure of optic vesicle formation results in anophthalmia without optic nerve formation. Anophthalmia is when a baby is born without one or both of their eyes.

Data were extracted from full text case reports exclusively describing SOX2 disorder (n=38) using exact string matching. Anophthalmia presents as a small, bony orbit, malar prominence, reduced palpebral fissure, short eyelids, and a constricted mucosal socket. 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. Mechanism of disease causation. Ages 0-3 years. Causes: SOX2: The most genetic based cause for anophthalmia is caused by the SOX2 gene.
