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]

The c.925G>A (p.G309S) alteration is located in exon 8 (coding exon 7) of the RUNX1 gene. This alteration results from a G to A substitution at nucleotide position 925, causing the glycine (G) at amino acid position 309 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

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. This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 309 of the RUNX1 protein (p.Gly309Ser). This variant is present in population databases (rs752288830, gnomAD 0.007%). 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: 573788). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on RUNX1 protein function. -
