NM_001754.5:c.743A>C

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 1P and 1B. PS4_SupportingBP4

This summary comes from the ClinGen Evidence Repository: NM_001754.5(RUNX1):c.743A>C (p.Asn248Thr) is a missense variant. This variant is present in two alleles in the South Asian population at a MAF of 0.0065% in gnomAD v2.1.1. This variant has been reported in one proband meeting at least one of the RUNX1-phenotypic criteria (Thrombocytopenia) (PS4_supporting). This missense variant has a REVEL score <0.50 (0.213) (BP4). In summary, this variant meets the criteria to be classified as a variant of uncertain significance. ACMG/AMP criteria applied, as specified by the Myeloid Malignancy Variant Curation Expert Panel for RUNX1: BP4, PS4_supporting.

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]
