| Hereditary neuropathy or pain disorder v3.89 | RTN2 |
Achchuthan Shanmugasundram changed review comment from: PMID:38527963 reported the identification of seven novel or ultra-rare homozygous loss-of-function RTN2 variants in 14 individuals from seven unrelated families with distal hereditary motor neuropathy. All affected individuals exhibited weakness in the distal upper and lower limbs, lower limb spasticity, hyperreflexia, with an onset in the first decade of life. Nerve conduction studies revealed axonal motor neuropathy with neurogenic changes in the electromyography. Characterisation of C. elegans RTN2 homolog loss-of-function variants demonstrated morphological and behavioural differences compared to the parental strain and treatment with an endoplasmic/sarcoplasmic reticulum Ca(2+) re-uptake inhibitor (2,5-di-tert-butylhydroquinone) rescued key phenotypic differences. Biallelic variants in RTN2 gene have not yet been associated with any phenotypes in OMIM or Gene2Phenotype, while monoallelic variants have been associated with spastic paraplegia (MIM #604805) in OMIM.

| Hereditary neuropathy or pain disorder v1.23 | SORD |
Ivone Leong Added comment: Comment on list classification: New gene added by Zornitza Stark (Australian Genomics) and recommended to be Green by David Hunt (Wessex Clinical Genetics Service). "Given that this is a potentially treatable neuropathy (https://www.ucl.ac.uk/ion/news/2020/may/sord-neuropathy-accelerated-journey-gene-identification-effective-treatment-patients), I think that SORD should be included in the ‘Hereditary neuropathy NOT PMP22 copy number’ gene panel." There is enough evidence to support a gene-disease association and this gene should be Green at the next review. |

| Hereditary neuropathy or pain disorder v0.29 | ATM | Louise Daugherty Added comment: Comment on list classification: 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/. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
