Genes affected

RUNX1 (HGNC:10471): (RUNX family transcription factor 1) Core binding factor (CBF) is a heterodimeric transcription factor that binds to the core element of many enhancers and promoters. The protein encoded by this gene represents the alpha subunit of CBF and is thought to be involved in the development of normal hematopoiesis. Chromosomal translocations involving this gene are well-documented and have been associated with several types of leukemia. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ClinGen Myeloid Malignancy Variant Curation Expert Panel

Jul 05, 2022

NM_001754.5(RUNX1):c.1034C>G (p.Pro345Arg) variant is present in gnomAD v2.1.1 and v3.1.2 (MAF 0.0001153, 1/8676 in African/ African American subpopulation) and does not meet any of the population criteria defined by the Myeloid Malignancy Variant Curation Expert Panel for RUNX1. REVEL score is not ≤0.50 (0.52). The variant has not been reported in patients with familial platelet disorder with a predisposition to hematologic malignancies in the literature, to the best of our knowledge. 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: N/A -

Invitae

Sep 19, 2023

This variant has not been reported in the literature in individuals affected with RUNX1-related conditions. ClinVar contains an entry for this variant (Variation ID: 571484). 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. 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. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces proline, which is neutral and non-polar, with arginine, which is basic and polar, at codon 345 of the RUNX1 protein (p.Pro345Arg). -
