Tracy Lester (Genetics laboratory, Oxford UK)
Affected individuals develop slowly progressive cerebellar ataxia, spasticity, and dorsal column dysfunction, sometimes with a mild cognitive deficit or decline. Onset can be in early adulthood, athough mostly it is before the age of 16. Several cases - greenCreated: 2 Sep 2019, 4:06 p.m. | Last Modified: 2 Sep 2019, 4:06 p.m.
