Invitae RCV001225786 SCV001398078 pathogenic Niemann-Pick disease, type C1 2023-07-14 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This variant, c.3460_3471del, results in the deletion of 4 amino acid(s) of the NPC1 protein (p.Leu1154_Leu1157del), but otherwise preserves the integrity of the reading frame. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with NPC1-related conditions. ClinVar contains an entry for this variant (Variation ID: 953488). This variant disrupts a region of the NPC1 protein in which other variant(s) (p.Asn1156Ser) have been determined to be pathogenic (PMID: 9211849, 16098014, 17160617, 23430855, 26666848, 27900365). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing.
