Hereditary neuropathy
Gene: SPG7Associated with relevant phenotype in OMIM and as definitive Gen2Phen gene. Numerous biallelic SPG7 variants have been reported (PMIDs: 9635427; 16534102; 17646629; 18200586, 20186691; 22571692) and at least five monoallelic SPG7 variants have been associated with Spastic paraplegia 7, autosomal recessive, OMIM:607259 (PMIDs: 18200586; 22571692). For this reason, the mode of inheritance for this gene should be BOTH monoallelic and biallelic (but BIALLELIC mutations cause a more SEVERE disease form) autosomal or pseudoautosomal.Created: 11 Apr 2023, 12:46 p.m. | Last Modified: 11 Apr 2023, 12:46 p.m.
Panel Version: 1.465
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.
