Variant summary

Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BS3BP4

This summary comes from the ClinGen Evidence Repository: The c.749G>A variant in RUNX1 is a missense variant predicted to cause substitution of arginine by histidine at amino acid 250 (p.R250H). A luciferase reporter assaying in U937 cells showed that this variant has normal transcriptional activity, and an EMSA assay using COS7 cells showed that this variant has normal DNA-binding and β-subunit interaction with normal nuclear localization in NIH3T3 cells, indicating that this variant does not impact protein function (PMID:23817177) (BS3). The computational predictor, REVEL, gives a score of 0.488, which is below the threshold of 0.50, evidence that suggests no impact on RUNX1 function (BP4). In summary, this variant meets the criteria to be classified as likely benign for hereditary thrombocytopenia and hematologic cancer predisposition syndrome based on the ACMG/AMP criteria applied, as specified by the ClinGen Myeloid Malignancy VCEP: BS3 and BP4.

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]
