Hereditary neuropathy or pain disorder
Gene: TFGThe mode of inheritance of this gene has been updated toBOTH monoallelic and biallelic, autosomal or pseudoautosomalfollowing NHS Genomic Medicine Service approval.Created: 1 Feb 2023, 10:16 a.m. | Last Modified: 1 Feb 2023, 10:16 a.m.
Panel Version: 2.18
Comment on mode of inheritance: MOI should be assessed at the next GMS panel review. If the decision is made to include genes on this panel that are associated with neuropathy as part of a more complex phenotype, rather than isolated neuropathy, the MOI should be updated from 'monoallelic' only to 'both mono- and biallelic' .
-----
Monoallelic variants are associated with an adult-onset motor and sensory neuropathy (MIM# 604484), a disorder that is relevant to this panel. Biallelic variants cause a HSP (MIM# 615658) which also has been shown to involve peripheral neuropathy in complex cases. Both phenotypes have a sufficient number of unrelated cases (>3) reported to warrant a Green rating (updated publications list).Created: 23 Aug 2021, 10:39 a.m. | Last Modified: 23 Aug 2021, 10:39 a.m.
