RCV003330340 | SCV004037389 | pathogenic | Hereditary antithrombin deficiency | 2023-09-21 | reviewed by expert panel | curation | The c.778A>T, p.Lys260* (NM_000488.3) in SERPINC1 is a nonsense variant predicted to cause a premature stop codon at codon 260 in biologically-relevant exon 5/7 that leads to nonsense mediated decay (PVS1). This variant is absent from gnomAD v2.1.1 (PM2_Supporting). This variant has been reported in 1 proband with antithrombin activity level of 48 meeting the SERPINC1-phenotypic criteria (AT level of <0.8 IU/mL, no repeat testing) (PS4_Supporting; Internal lab contributors). In summary, this variant meets criteria to be classified as pathogenic. ACMG/AMP criteria applied, as specified by the Thrombosis Variant Curation Expert Panel for SERPINC1: PVS1, PM2_Supporting, PS4_Supporting. |
