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]

Inborn genetic diseases Uncertain:1
Jan 31, 2025
Ambry Genetics
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.L313R variant (also known as c.938T>G), located in coding exon 7 of the RUNX1 gene, results from a T to G substitution at nucleotide position 938. The leucine at codon 313 is replaced by arginine, an amino acid with dissimilar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear.

Significance:Uncertain significance
Review Status:reviewed by expert panel
Collection Method:curation

NM_001754.5(RUNX1):c.938T>G (p.Leu313Arg) is a missense variant. This missense variant has a REVEL score <0.50 (0.202) (BP4) and SpliceAI ≤0.20 (0.01 -29bp Donor Gain). 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.

Hereditary thrombocytopenia and hematological cancer predisposition syndrome associated with RUNX1 Uncertain:1

Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces leucine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 313 of the RUNX1 protein (p.Leu313Arg). This variant is present in population databases (rs766264813, gnomAD 0.01%). 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: 239058). 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 with a negative predictive value of 80%. 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.
