ClinGen Myeloid Malignancy Variant Curation Expert Panel RCV004595583 SCV005088312 uncertain significance Hereditary thrombocytopenia and hematologic cancer predisposition syndrome 2024-07-11 reviewed by expert panel curation NM_001754.5(RUNX1):c.763C>A (p.His255Asn) is a missense variant which has a REVEL score <0.50 (0.38) and a SpliceAI score ≤ 0.20 (0.02) (BP4). 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
Labcorp Genetics (formerly Invitae), Labcorp RCV001233271 SCV001405858 uncertain significance Hereditary thrombocytopenia and hematological cancer predisposition syndrome associated with RUNX1 2022-12-25 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. 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 not expected to disrupt RUNX1 protein function. ClinVar contains an entry for this variant (Variation ID: 959847). This variant has not been reported in the literature in individuals affected with RUNX1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces histidine, which is basic and polar, with asparagine, which is neutral and polar, at codon 255 of the RUNX1 protein (p.His255Asn).
