James Polke (Neurogenetics Laboratory, Institute of Neurology, London)
On Sheffield panel. Thiffault et al. (2006) reported 23 French Canadian individuals from 17 families with spastic ataxia and brain white matter changes and ataxic gait. 5 DM reported in HGMD but 3 (with the relevant phenotype) are large duplications which may not be detected. Likely to be in HSP panel also.Created: 27 Apr 2019, 7:39 p.m.

As discussed with the GMS Neurology Specialist Test Group webex call 26th July 2019: The Specialist Test Group all agreed that there is enough evidence to rate this gene GreenCreated: 1 Aug 2019, 3:43 p.m. | Last Modified: 1 Aug 2019, 3:43 p.m.

Looks like variants reported in the literature are complex deletion/duplication events - not sure how well short-read sequencing will cope with theseCreated: 15 Apr 2019, 10:06 a.m.
