Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV001733392 SCV001983597 likely pathogenic Congenital amegakaryocytic thrombocytopenia 2021-09-30 criteria provided, single submitter clinical testing Variant summary: MPL c.367C>T (p.Arg123X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory. The variant was absent in 251470 control chromosomes (gnomAD). The variant, c.367C>T, has been reported in the literature in a compound heterozygous individual affected with Congenital Amegakaryocytic Thrombocytopenia (Germeshausen_2006, Germeshausen_2020). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as likely pathogenic.
