Green List (high evidence)

Comment on list classification: As reviewed by Alexander Rossor, peripheral neuropathy is a part of Refsum disease (MIM #266500). OMIM record lists peripheral sensorimotor neuropathy as one of the clinical manifestations. In addition, PMID:20301527 reports that polyneuropathy is present in ~70% of cases with Refsum disease.

Hence, this gene can be promoted to green rating in the next GMS update.

I don't know

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/.

Green List (high evidence)

Refsums disease is a well established (historical) cause of peripheral neuropathy. It is treatable and has to be included in the R78 panel now that it includes complex phenotypes
