Invitae | RCV000816232 | SCV000956730 | pathogenic | Autosomal recessive axonal neuropathy with neuromyotonia | 2022-11-07 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the HINT1 protein in which other variant(s) (p.His112Asn) have been determined to be pathogenic (PMID: 16835243, 22961002, 31088288). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. ClinVar contains an entry for this variant (Variation ID: 659256). This variant has not been reported in the literature in individuals affected with HINT1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.0009%). This sequence change results in a frameshift in the HINT1 gene (p.Val111Thrfs*32). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 16 amino acid(s) of the HINT1 protein and extend the protein by 15 additional amino acid residues. |
