Variant summary

Our verdict is Benign. The variant received -11 ACMG points: 0P and 11B. BP7BA1BP2BP4

This summary comes from the ClinGen Evidence Repository: This synonymous variant is present in gnomAD (v2 and v3) at an allele frequency >0.15% with at least 5 alleles in any general continental population (BA1); in addition, the variant was found in homozygosity in the population database (BP2). The 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 evolutionary conservation prediction algorithms predict the site as being not highly conserved (PhyloP score: 1.01 [-14.1;6.4]) (BP4; BP7). In summary, the clinical significance of this variant is benign. ACMG/AMP criteria applied, as specified by the ClinGen Myeloid Malignancy Variant Curation Expert Panel for RUNX1: BA1, BP2, 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]

Illumina Laboratory Services, Illumina

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. -

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. -

This synonymous variant is present in gnomAD (v2 and v3) at an allele frequency >0.15% with at least 5 alleles in any general continental population (BA1); in addition, the variant was found in homozygosity in the population database (BP2). The 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 evolutionary conservation prediction algorithms predict the site as being not highly conserved (PhyloP score: 1.01 [-14.1;6.4]) (BP4; BP7).
