Variant summary
Our verdict is Uncertain significance. The variant received -1 ACMG points: 0P and 1B. BP4
This summary comes from the ClinGen Evidence Repository: NM_001754.4(RUNX1):c.56G>A (p.Arg19Lys) is a missense variant predicted to cause substitution of arginine by lysine at amino acid 19 (p.R19K); note that this variant is in the 5' UTR, c.-161732G>A, of NM_001001890.3. The variant has been reported in a 69-year-old patient with NPM1-mutated, cytogenetically normal AML at a VAF=53% (PMID:31367767) and in a patient with CMML (PMID:24030381, Supplementary Table 2); however, germline origin is unclear for these cases. The highest population minor allele frequency in gnomAD v2 is 0.006966% (9/129192 alleles) in the non-Finnish European population, and the variant has also been reported in 1/1358 controls from a study evaluating 57 individuals with cutaneous melanoma and 2 other primaries (PMID:29641532, Supplementary Table 3). To our knowledge, functional assays have not been reported for this variant, but the computational predictor REVEL gives a score of 0.456, which is below the threshold of 0.50, and the splice site predictor SpliceAI indicated that the variant has no impact on splicing, evidence that does not predict a damaging effect on RUNX1 function (BP4). In summary, this variant meets the criteria to be classified as a variant of uncertain significance for autosomal dominant hereditary thrombocytopenia and hematologic cancer predisposition syndrome based on the ACMG/AMP criteria applied, as specified by the ClinGen Myeloid Malignancy-VCEP: BP4.
