ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories RCV000757724 SCV000886060 pathogenic not provided 2018-01-25 criteria provided, single submitter clinical testing The RUNX1 c.958C>T; p.Arg320Ter variant, also known as R292X, is reported in the germline of individuals with familial platelet disorder with associated myeloid malignancies (FPDMM) (Owen 2008, Patton 2007, Rossini 2012). This variant is absent from the general population databases (1000 Genomes Project, Exome Variant Server, Genome Aggregation Database), indicating it is not a common polymorphism. This variant induces an early termination codon; since it occurs toward the end of the penultimate exon the transcript is less likely to be subject to nonsense-mediated decay and more likely to yield a truncated protein, but mRNA nonsense-mediated decay cannot be ruled out. Based on available information, this variant is considered pathogenic. REFERENCES Owen CJ et al.
