Description

This sequence change creates a premature translational stop signal (p.Phe126Leufs*5) in the MPL gene. It is expected to result in an absent or disrupted protein product. This variant is present in population databases (rs587778515, ExAC 0.01%). This variant has been observed in several individuals affected with congenital amegakaryocytic thrombocytopenia (PMID: 11133753, 28859041, 16470591). ClinVar contains an entry for this variant (Variation ID: 265249). Loss-of-function variants in MPL are known to be pathogenic (PMID: 8073287, 11133753). For these reasons, this variant has been classified as Pathogenic.
