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/.
