Labcorp Genetics (formerly Invitae), Labcorp RCV002975940 SCV003286328 uncertain significance Hereditary antithrombin deficiency 2022-02-04 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This variant results in an extension of the SERPINC1 protein. Other variant(s) that result in a similarly extended protein product (c.1394A>C (p.*465Serext*28)) have been observed in individuals with SERPINC1-related disease (PMID: 22398878). This suggests that these extensions may be clinically significant. This protein extension has been observed in individual(s) with clinical features of antithrombin III deficiency (Invitae). This sequence change disrupts the translational stop signal of the SERPINC1 mRNA. It is expected to extend the length of the SERPINC1 protein by an uncertain number of additional amino acid residues.
