Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP7 BP4

This summary comes from the ClinGen Evidence Repository: This synonymous variant is predicted by SSF and MES to lead to either an increase in the canonical splice site score or a decrease of the canonical splice site score by no more than 10% and no putative cryptic splice sites are created, and although evolutionary conservation prediction algorithms predict the site as being weakly conserved (PhyloP score: 1.66 > 0.1 [-14.1;6.4]), the variant is the reference nucleotide in one primate and/or three mammal species (BP4+BP7). In summary, this variant meets criteria to be classified as likely benign. ACMG/AMP criteria applied, as specified by the ClinGen 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]
