Variant summary

Our verdict is Benign. Variant got -9 ACMG points: 0P and 9B. BP4BA1

This summary comes from the ClinGen Evidence Repository: This c.1190A>G (p.Gln397Arg) missense variant has a MAF of 0.003624 (0.3624%, 53/14624, 202938 alleles) in the East Asian subpopulation of the gnomAD v2 cohort, which is ≥ 0.0015 (0.15%) (BA1). The high allele frequency accounts for reports of this variant in affected individuals: 2 heterozygous patients with AML (PMID:19808697), a homozygous patient with personal and family history of thrombocytopenia (PMID:30103613), and other reports of this variant in patients with MDS, AML, and T-ALL that have not been confirmed to be of germline origin (PMID:17910630, 24523240, 24792891, 24850867, 28157215, 29279377). Furthermore, an abstract indicated that a dual luciferase assay used to assess this variant's transactivation ability in K562 cells was normal, although this data was not published in a peer-reviewed format (Huang et al., 2009, ASH Abstract 3468 - https://ashpublications.org/blood/article/114/22/3468/132805/High-Frequency-of-C-Terminal-Frame-Shift-Mutations). This missense variant have a REVEL score <0.5 (0.238), and is not predicted by SpliceAI, MES, or SSF-like to have a splicing impact (BP4). 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 and 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]
