Variant summary

Our verdict is Benign. Variant got -6 ACMG points: 0P and 6B. BP4BS1BP7

This summary comes from the ClinGen Evidence Repository: The MAF of the NM_001754.4(RUNX1):c.423G>A (p.Ser141=) variant is 0.0001633 (0.016%, 5/30614 alleles, 251394 alleles) in the South Asian cohort (gnomAD), 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 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: -1.49 < 0.1 [-14.1;6.4]) (BP7). 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, 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]

Inborn genetic diseases Benign:1
Feb 16, 2025
Ambry Genetics
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. -
