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. The Human Phenotype Ontology (HPO) enables use of precise, standardized, computationally accessible terms to describe phenotypic abnormalities.

How do you know if your baby has anophthalmia or microphthalmia? Anophthalmia-esophageal atresia-genital abnormalities (AEG) syndrome was previously reported to be a distinct disorder, but is now known to be associated in some individuals with heterozygous pathogenic loss-of-function variants in SOX2 [Williamson et al 2006, Zenteno et al 2006]; thus, it appears that esophageal atresia with or without tracheoesophageal fistula is a feature of SOX2 disorder and not a separate condition. Contrary to popular belief, AAC devices do not hinder verbal development of speech, but rather support optimal speech and language development. Hussenet T et al: 18268498: 2008: SOX2 is frequently downregulated in gastric cancers and inhibits cell growth through cell-cycle arrest .
