ClinGen Myeloid Malignancy Variant Curation Expert Panel RCV004773243 SCV005382715 uncertain significance Hereditary thrombocytopenia and hematologic cancer predisposition syndrome 2024-10-29 reviewed by expert panel curation NM_001754.5(RUNX1):c.1420G>A (p.Glu474Lys) is a missense variant which has a REVEL score < 0.50 (0.407) and a SpliceAI score ≤ 0.20 (0.0) (BP4). This variant is completely absent from all population databases with at least 20x coverage for RUNX1 (PM2_Supporting). In summary, the clinical significance of this variant is uncertain. ACMG/AMP criteria applied, as specified by the Myeloid Malignancy Variant Curation Expert Panel for RUNX1: BP4, PM2_supporting.
Labcorp Genetics (formerly Invitae), Labcorp RCV001037101 SCV001200498 uncertain significance Hereditary thrombocytopenia and hematological cancer predisposition syndrome associated with RUNX1 2019-01-21 criteria provided, single submitter clinical testing 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with RUNX1-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the ExAC database. This sequence change replaces glutamic acid with lysine at codon 474 of the RUNX1 protein (p.Glu474Lys). The glutamic acid residue is moderately conserved and there is a small physicochemical difference between glutamic acid and lysine.
