Comment on mode of inheritance: Dystonia association with monoallelic variants is well-established with multiple cases reported worldwide (OMIM:128100). Biallelic variants cause a more severe phenotype of congenital arthrogryposis (OMIM:618947) and movement impairments including dystonia are also common (PMIDs: 29053766, 30244176). For this reason the MOI was updated from 'monoallelic' only to 'both mono- and biallelic (biallelic more severe)'.Created: 28 Mar 2022, 2:07 p.m. | Last Modified: 28 Mar 2022, 2:07 p.m.

Comment from the Parkinson panel: Monoallelic mutations cause primary torsion dystonia (DYT1), early-onset isolated dystonia, plus plus childhood/adolescence onset, plus plus focal (but can be generalized). No other neurologic abnormalities are present. Disease severity varies considerably even within the same family. Isolated writer's cramp may be the only sign. One common mutation (c.907_909delGAG). Reduced penetrance. PMID 20301665 (gene review). Consider moving this gene to the dystonia panel?Created: 15 Dec 2016, 11:11 a.m.
