Variant summary

Our verdict is Benign. The variant received -10 ACMG points: 0P and 10B. BP7BA1BP4

This summary comes from the ClinGen Evidence Repository: NM_001754.5(RUNX1):c.303G>T (p.Val101=) is a synonymous variant. MAF of 0.00671 (0.671%, 167/24878, 167 alleles) in the African subpopulation of the gnomAD cohort is ≥ 0.0015 (0.15%) (BA1). Not a missense variant, therefore, no REVEL score and SpliceAI is ≤0.50 (0.00) (BP4). Evolutionary conservation prediction algorithms predict the site as not being conserved (PhyloP score 1.4739 < 2.0 or the variant is the reference nucleotide in one primate and/or three mammal species) (BP7). In summary, this variant meets criteria to be classified as benign. ACMG/AMP criteria applied, as specified by the Myeloid Malignancy Variant Curation Expert Panel for RUNX1: BA1, BP4, 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]

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
