Variant summary

Our verdict is Benign. The variant received -11 ACMG points: 0P and 11B. BP7BP2BP4BA1

This summary comes from the ClinGen Evidence Repository: The NM_001754.4:c.351+15A>G variant has a MAF of 0.00809 (0.809%, 524/64,760 alleles) in the European (Non-Finnish) subpopulation of the ExAC cohort that is ≥ 0.0015 (0.15%) (BA1). This variant is detected in homozygous state (8) in gnomAD population database (BP2). This intronic 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 (BP4). In addition, evolutionary conservation prediction algorithms predict the site as not being highly conserved (PhyloP score -1.34728 < 0.1) (BP7). In summary, this variant meets criteria to be classified as benign. ACMG/AMP criteria applied, as specified by the ClinGen Myeloid Malignancy Variant Curation Expert Panel for RUNX1: BA1, BP2, 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:Benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
