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]

Hereditary thrombocytopenia and hematologic cancer predisposition syndrome Uncertain:1
Uncertain significance, reviewed by expert panelcurationClinGen Myeloid Malignancy Variant Curation Expert PanelNov 13, 2023NM_001754.5(RUNX1):c.899C>T (p.Thr300Met) is a missense variant.

This missense variant has a REVEL score <0.50 (0.423)(BP4). There is no splicing effect predicted (SpliceAI=0). The variant has not been reported in patients with the RUNX1-defined phenotype.

Hereditary thrombocytopenia and hematological cancer predisposition syndrome associated with RUNX1 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 08, 2023This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 300 of the RUNX1 protein (p.Thr300Met). This variant is present in population databases (rs758682659, gnomAD 0.005%). 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: 409809). 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. -
