Genet. These children should be considered at risk for status dystonicus, which can be triggered by any major physiologic stress and can lead to protracted periods of hospitalization and critical care.

See Quick Reference for an explanation of nomenclature. Novel SOX2 mutation in autosomal dominant cataract-microcornea syndrome The SOX2 anophthalmia syndrome is emerging as a clinically recognizable disorder that has been identified in 10-15% of individuals with bilateral anophthalmia. 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]. This gene provides instructions for making a protein that plays a critical role in the formation of many different tissues and organs during embryonic development. If you have it, your cornea doesnt reach 10 mm in diameter even when youre an adult. Seizures were observed in 22 individuals. affected daughters. As SOX2 is a single-exon gene, there are no alternative splice transcripts and it is not subject to nonsense-mediated decay; however, loss-of-function variants have been observed throughout the exon.
