Hereditary neuropathy or pain disorder
Gene: PLP1
Numerous PLP1 variants have been associated with OMIM:312080 and OMIM:312920. This gene should be green on this panel, as the panel scope now includes complex phenotypes.Created: 13 May 2024, 8:57 a.m. | Last Modified: 13 May 2024, 8:57 a.m.
Panel Version: 4.11
Mode of inheritance
X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males)
Phenotypes
Spastic paraplegia 2, X-linked, OMIM:312920; Pelizaeus-Merzbacher disease, OMIM:312080
Gene rated Amber : From feedback from Genomics England Clinical team (Anna de Burca and Meriel McEntagart): Extension of panel scope - minor feature / Broader phenotype: Pelizaeus-Merbacher/Spastic paraplegia 2 - is neuropathy a feature?Created: 7 Dec 2019, 12:03 a.m. | Last Modified: 7 Dec 2019, 12:03 a.m.

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.
