Labcorp Genetics (formerly Invitae), Labcorp RCV001994502 SCV002234179 pathogenic Congenital sideroblastic anemia-B-cell immunodeficiency-periodic fever-developmental delay syndrome 2022-07-19 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Ser418Metfs*9) in the TRNT1 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 17 amino acid(s) of the TRNT1 protein. For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the TRNT1 protein in which other variant(s) (p.Ser418Lysfs*9:) have been determined to be pathogenic (PMID: 25193871, 26494905, 29358286). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. ClinVar contains an entry for this variant (Variation ID: 1452239). This variant has not been reported in the literature in individuals affected with TRNT1-related conditions. This variant is not present in population databases (gnomAD no frequency).
