Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 1P and 2B. BP7 PM2_Supporting BP4

This summary comes from the ClinGen Evidence Repository: NM_001754.5(RUNX1):c.1311C>G (p.Thr437=) is s synonymous variant. Computation evidence is not calculable for the effect of this SYNONYMOUS variant on protein function. The REVEL score is not calculable. Splice AI predicts a 0.00 score for acceptor loss, donor loss, acceptor gain, and donor gain(BP4). Evolutionary conservation prediction algorithms predict the site as not being conserved (PhyloP score -3.62398 < 2.0)(BP7). This synonymous variant is absent from all examined population databases with at least 20x coverage for RUNX1(PM2_supporting). 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, BP7, PM2_supporting LINK:https://erepo.genome.network/evrepo/ui/classification/CA512341068/MONDO:0011071/008

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]
