Variant summary

Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BS1

This summary comes from the ClinGen Evidence Repository: The NM_001754.4:c.698G>A (p.Arg233His) variant has a MAF of 0.00142 (0.142%, 34/23,970 alleles) in the African subpopulation of the gnomAD cohort that is between 0.00015 (0.015%) and 0.0015 (0.15%) (BS1). We allow a variant to reach a likely benign classification based on BS1 alone if there is no contradictory evidence supporting pathogenicity. 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: BS1.

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 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.
