Invitae RCV000649922 SCV000771758 likely pathogenic Charcot-Marie-Tooth disease axonal type 2P 2023-05-19 criteria provided, single submitter clinical testing ClinVar contains an entry for this variant (Variation ID: 540008). This protein change is located in a region of the LRSAM1 protein where a significant number of LRSAM1 nonsense and frameshift mutations have been reported in autosomal dominant Charcot-Marie-Tooth disease (PMID: 33414056, 31211173, 29341362). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This variant has not been reported in the literature in individuals affected with LRSAM1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change results in a frameshift in the LRSAM1 gene (p.Gln701Argfs*34). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 23 amino acid(s) of the LRSAM1 protein and extend the protein by 10 additional amino acid residues.
