RCV001070797 | SCV001236067 | pathogenic | Transcobalamin II deficiency | 2019-03-11 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in TCN2 are known to be pathogenic (PMID: 7980584, 20352340). This variant has not been reported in the literature in individuals with TCN2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Gly79Valfs*7) in the TCN2 gene. It is expected to result in an absent or disrupted protein product. |
