RCV004695233 | SCV005196496 | uncertain significance | Hereditary thrombocytopenia and hematologic cancer predisposition syndrome | 2024-07-17 | reviewed by expert panel | curation | NM_001754.5(RUNX1):c.475A>G (p.Asn159Asp) is a missense variant affecting one of the residues within the runt homology domain (AA 89-204) (PM1_supporting). This variant is completely absent from all population databases with at least 20x coverage for RUNX1 (PM2_supporting). This missense variant has a REVEL score >0.88 (0.956) (PP3). Transactivation assays demonstrate normal transactivation at 80.43% (80-115% of wt), suggesting functional similarity to the wild type (BS3_Supporting; PMID: 34166225). In summary, the clinical significance of this variant is uncertain. ACMG/AMP criteria have been applied, as specified by the Myeloid Malignancy Variant Curation Expert Panel for RUNX1: PM1_supporting, PM2_supporting, BS3_supporting, PP3. |

RCV001229885 | SCV001402346 | uncertain significance | Hereditary thrombocytopenia and hematological cancer predisposition syndrome associated with RUNX1 | 2024-05-22 | criteria provided, single submitter | clinical testing | This sequence change replaces asparagine, which is neutral and polar, with aspartic acid, which is acidic and polar, at codon 159 of the RUNX1 protein (p.Asn159Asp). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with glioma and/or acute lymphoblastic leukemia (PMID: 26580448, 34166225). ClinVar contains an entry for this variant (Variation ID: 956982). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt RUNX1 protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects RUNX1 function (PMID: 34166225). 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. |
