Role of SOX2 mutations in human hippocampal malformations and epilepsy. The majority of affected individuals have some evidence of hypothalamic-pituitary axis dysfunction when detailed measurement of growth hormone and gonadotropins is undertaken [Tziaferi et al 2008]. Gene-targeted deletion/duplication testing will detect deletions ranging from a single exon to a whole gene; however, breakpoints of large deletions and/or deletion of adjacent genes (e.g., those described by Suzuki et al [2014]) may not be detected by these methods [Chassaing et al 2014]. Multiple pages were reviewed for this article. Methods used may include a range of techniques such as quantitative PCR, long-range PCR, multiplex ligation-dependent probe amplification (MLPA), and a gene-targeted microarray designed to detect single-exon deletions or duplications.

Dystonia may worsen & can show acute change to status dystonicus, which should be considered a medical emergency. Heterozygous, de novo, loss-of-function mutations in SOX2 have been shown to cause bilateral anophthalmia. Stark Z, Storen R, Bennetts B, Savarirayan R, Jamieson RV. Certain defects such as those of the heart, palate and esophagus can be surgically repaired. 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. 2008;2(4-5):194-9. doi: 10.1159/000152035.
