Variant summary

Our verdict is Likely benign. Variant got -5 ACMG points: 0P and 5B. BP4BS1

This summary comes from the ClinGen Evidence Repository: The MAF of the synonymous variant, NM_001754.4:c.654C>T (p.Ser218=), is 0.00105 (0.1%, 36/34418 alleles) in the Latino subpopulation of the gnomAD cohort, which is between 0.00015 (0.015%) and 0.0015 (0.15%) (BS1). This synonymous variant is predicted by SSF and MES to lead to 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 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: BS1, BP4.

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]

Benign:3

Benign, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Jan 13, 2018	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. -
