RCV003598065 | SCV004469267 | pathogenic | Transcobalamin II deficiency | 2023-10-28 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Thr333Asnfs*6) in the TCN2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in TCN2 are known to be pathogenic (PMID: 7980584, 20352340). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with TCN2-related conditions. ClinVar contains an entry for this variant (Variation ID: 1675884). For these reasons, this variant has been classified as Pathogenic. |
