ClinGen Myeloid Malignancy Variant Curation Expert Panel RCV000824700 SCV000965612 pathogenic Hereditary thrombocytopenia and hematological cancer predisposition syndrome associated with RUNX1 2019-07-29 reviewed by expert panel curation The NM_001754.4:c.601C>T (p.Arg201Ter) variant is a nonsense variant that is predicted to introduce a premature stop codon and expected to result in nonsense-mediated mRNA decay (PVS1). This variant has been reported in four probands meeting at least one of the RUNX1-phenotypic criteria (PS4; PMIDs: 10508512; 19387465; 20549580; 28513614). The variant was found to co-segregate with disease in multiple affected family members, with 14 meioses observed in across 4 families (PP1_Strong; PMID: 10508512; 19387465; 20549580; 28513614). The variant is completely absent from all population databases with at least 20x coverage for RUNX1 (PM2). In summary, this variant meets criteria to be classified as pathogenic. ACMG/AMP criteria applied, as specified by the Myeloid Malignancy Variant Curation Expert Panel for RUNX1: PVS1, PS4, PP1_Strong, PM2.

Genetic Services Laboratory, University of Chicago RCV001753852 SCV002067300 pathogenic not provided 2019-04-20 criteria provided, single submitter clinical testing DNA sequence analysis of the RUNX1 gene demonstrated a sequence change, c.601C>T, which results in the creation of a premature stop codon at amino acid position 201, p.Arg201*. This pathogenic sequence change is predicted to result in an abnormal transcript, which may be degraded, or may lead to the production of a truncated RUNX1 protein with potentially abnormal function. This pathogenic sequence change is absent from population databases such as ExAC and gnomAD. This pathogenic sequence change has previously been described in multiple patients with RUNX1-related thrombocytopenia (Ripperger et al., 2009; Yoshima et al., 2016; Tawana et al., 2017).

Invitae RCV000824700 SCV003443836 pathogenic Hereditary thrombocytopenia and hematological cancer predisposition syndrome associated with RUNX1 2022-08-20 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 376018). This premature translational stop signal has been observed in individual(s) with acute myelogenous leukemia and/or familial thrombocytopenia (PMID: 10508512). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Arg201*) in the RUNX1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in RUNX1 are known to be pathogenic (PMID: 18723428, 24100448).
PreventionGenetics, part of Exact Sciences RCV003932542 SCV004749994 pathogenic RUNX1-related disorder 2024-02-16 criteria provided, single submitter clinical testing The RUNX1 c.601C>T variant is predicted to result in premature protein termination (p.Arg201*). This variant has been reported in several families with familial platelet disorder and hematologic malignancies (see for example Sood et al. 2017. PubMed ID: 28179279). Other RUNX1 gene variants that cause premature protein termination of the RUNX1 protein have been reported in numerous patients with thrombocytopenia and myeloid malignancies (Song et al. 1999. PubMed ID: 10508512; Buijs et al. 2012. PubMed ID: 22430633; Shiba et al. 2012. PubMed ID: 22138511). This variant has not been reported in a large population database, indicating this variant is rare. Nonsense variants in RUNX1 are expected to be pathogenic. In summary, the RUNX1 gene variant p.Arg201* is the type of variant expected to be a primary cause of disease and may also be associated with myeloid malignancy predisposition.

Ambry Genetics RCV004022198 SCV005018254 pathogenic Inborn genetic diseases 2023-12-20 criteria provided, single submitter clinical testing The p.R201* pathogenic mutation (also known as c.601C>T), located in coding exon 5 of the RUNX1 gene, results from a C to T substitution at nucleotide position 601. This changes the amino acid from an arginine to a stop codon within coding exon 5. This alteration has been reported in multiple individuals in the literature with a personal and/or family history of thrombocytopenia and/or hematologic malignancies (examples: Tawana K et al. Eur J Hum Genet. 2017 Aug;25(8):1020-1024; Ansar S et al. Genet Med. 2022 Nov;24(11):2367-2379; Liu C et al. EJHaem . 2023 Feb;4(1):145-152). In addition, this variant was reported to segregate with disease in multiple affected family members (Tawana K et al. Eur J Hum Genet. 2017 Aug;25(8):1020-1024; Liu C et al. EJHaem. 2023 Feb;4(1):145-152). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation.
