Adult onset dystonia, chorea or related movement disorder
Gene: HEXA
This panel was initially created as a merge of genomic entities from the following Rare Disease 100K panels - Early onset dystonia (v1.76, code 192) - Parkinson Disease and Complex Parkinsonism (v1.64, code 39) - Brain channelopathy (v1.48, code 90) - Structural basal ganglia disorders (v1.10, code 180). This gene was RED and external expert review from South West GLH for GMS Neurology specialist test group for R56 agrees this gene should remain REDCreated: 19 Jun 2019, 4:16 p.m.
