Mode of inheritance
BOTH monoallelic and biallelic, autosomal or pseudoautosomal
Comment on mode of inheritance: Should be updated from biallelic only to both mono- and biallelic at the next GMS panel update.
Dystonia is an established feature of AGS6 (MIM# 615010) associated with AR variants in this gene. Overall the AD condition (dyschromatosis symmetrica hereditaria, MIM# 127400) often presents with changes in skin pigmentation as the only sign of disease. However, there have also been reports of neurologic deficits including ID, developmental regression, brain calcification, seizures and dystonia in some affected individuals, particularly with the Gly1007Arg variant (PMID: 16225627; 16817193; 19017046). Although the penetrance of extracutaneous features is reduced, there is value in testing heterozygous ADAR variants on these panels to ensure syndromic cases are not missed if not tested in the context of the skin phenotype.Created: 25 Oct 2022, 11:44 a.m. | Last Modified: 25 Oct 2022, 11:44 a.m.
