Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 0P and 2B. BP4 BP7

This summary comes from the ClinGen Evidence Repository: NM_001754.5(RUNX1):c.492C>T (p.Val164=) is a synonymous variant. No REVEL score because a synonymous variant and SpliceAI is ≤0.20( 0.01 Donor Loss -16bp and 0.11 Donor Gain 7bp) (BP4). Evolutionary conservation prediction algorithms predict the site as not being conserved (PhyloP 1.91014 ≤ 2.0) meeting BP7. In summary, this variant meets criteria to be classified as likely benign. ACMG/AMP criteria applied, as specified by the Myeloid Malignancy Variant Curation Expert Panel for RUNX1: BP4 and BP7.

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]

ENSG00000286153 (HGNC:56821): (RUNX1 antisense RNA 1)
