Variant summary

Our verdict is Benign. Variant got -9 ACMG points: 0P and 9B. BA1BP4

This summary comes from the ClinGen Evidence Repository: The NM_001754.4:c.1396A>T variant that results in a Met466Leu missense change has an MAF of 0.001761 (0.1%, 23/13058 alleles) in the East Asian subpopulation of the gnomAD v2.1.1 cohort, which is >0.0015 (0.15%) (BA1). This missense variant has a REVEL score <0.15 (0.149) and SSF and MES predict no effect on splicing (BP4). The variant has not been reported in the germ line of patients with familial platelet disorder with predisposition to hematologic malignancies in the literature, to the best of our knowledge. In summary, this variant meets criteria to be classified as benign. ACMG/AMP criteria applied, as specified by the Myeloid Malignancy Variant Curation Expert Panel for RUNX1: BA1, 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]

Hereditary thrombocytopenia and hematological cancer predisposition syndrome associated with RUNX1

Uncertain:1Benign:1

Uncertain significance, criteria provided, single submitter	clinical testing	ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	Sep 19, 2018	The RUNX1 c.1396A>T; p.Met466Leu variant (rs762213305), to our knowledge, is not reported in the medical literature but is reported as uncertain significance in ClinVar (Variation ID: 463982). This variant is found in the East Asian population with an allele frequency of 0.19% (23/12,256 alleles) in the Genome Aggregation Database. The methionine at codon 466 is moderately conserved, but computational analyses (SIFT: tolerated, PolyPhen-2: possibly damaging) predict conflicting effects of this variant on protein structure/function. Due to limited information, the clinical significance of the p.Met466Leu variant is uncertain at this time. -

This alteration is classified as 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. -
