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.
Dravet syndrome in particular appears to be associated with ataxia. Plenty of cases in lit although I'd query whether seizures are likely to be a more prominent part of phenotypeCreated: 15 Apr 2019, 10:06 a.m.
