Hereditary neuropathy
Gene: PLP1
The Neurology Specialist Test Group agreed that this gene was recommended for the WGS panel based on a broader phenotype view to include conditions where neuropathy is part of a more complex phenotype or where there is overlap with another neurological presentation eg. HSP. This panel includes conditions where neuropathy is part of a more complex phenotype or where there is overlap with another neurological presentation. This panel as going to be used for R78, 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 and as a result a new panel was created https://panelapp.genomicsengland.co.uk/panels/846/ for this purpose.Created: 7 Dec 2019, 6:08 p.m. | Last Modified: 7 Dec 2019, 6:08 p.m.
