Labcorp Genetics (formerly Invitae), Labcorp RCV003064652 SCV003444342 pathogenic Transcobalamin II deficiency 2024-01-05 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Arg313*) 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 present in population databases (rs747257199, gnomAD 0.004%). This premature translational stop signal has been observed in individual(s) with clinical features of transcobalamin II deficiency (PMID: 2430590). ClinVar contains an entry for this variant (Variation ID: 2138436). For these reasons, this variant has been classified as Pathogenic.
