G59 mutation clearly causes dhmn with vocal cord palsy. Multiple unrelated families

Natalie Forrester (SWGLH - Bristol Genetics)

Green List (high evidence)

In Bristol seen 2 previously reported pathogenic variants (segregating in several family members) and one likely pathogenic variant (all had motor neuropathy). Should be included to pick up patients perhaps with ALS/MND who are presenting with motor neuropathy signs. PMID:27025386 (2016) - Study includes the report of a 12 year old boy with pure distal hereditary motor neuropathy with upper and lower limb weakness. PMID: 28251916 - de novo variant in patient with pes cavus, ataxia and dystonia. PMID: 24627108 - patient with HMSN2 (apparently segregating but cannot see pedigree)
Created: 29 Apr 2019, 12:30 p.m.

Panel Version: 0.36
Comment on list classification: This gene has changed ratings because the panel for R78 was going to be a broad panel (to include conditions where neuropathy is part of a more complex phenotype or where there is overlap with another neurological presentation eg. HSP) but subsequently during the follow up call on 21st June with the Test Group it was agreed that it was more clinically relevant for R78 to be restricted to genes that are associated with isolated neuropathy, which this panel represents. For genes that represent the broader phenotype see https://panelapp.genomicsengland.co.uk/panels/85/.
