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]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.V452L variant (also known as c.1354G>C), located in coding exon 8 of the RUNX1 gene, results from a G to C substitution at nucleotide position 1354. The valine at codon 452 is replaced by leucine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -

NM_001754.5(RUNX1):c.1354G>C (p.Val452Leu) is a missense variant which has a REVEL score < 0.50 (0.044), and a SpliceAI score ≤ 0.20 (0.0) (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. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant has not been reported in the literature in individuals affected with RUNX1-related conditions. This sequence change replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 452 of the RUNX1 protein (p.Val452Leu). This variant is not present in population databases (gnomAD no frequency). ClinVar contains an entry for this variant (Variation ID: 856836). 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. -
