Hereditary ataxia with onset in adulthood
Gene: GLRA1
Review and rating from Tracy Lester (Oxford Medical Genetics Laboratories Oxford University Hospitals NHS Foundation Trust) on behalf of Wessex and West Midlands GLH for GMS Neurology specialist test group.Created: 15 Apr 2019, 10:21 a.m.
Phenotype on OMIM doesn't specificially mention ataxia or cerebellar abnormalities but described movement disorder could be confused. Looks like loss of function variants are only associtaed with the AR form (not halpoinsufficient)Created: 15 Apr 2019, 10:06 a.m.
