Description

NM_005373.2(MPL):c.1058delA(H353Pfs*16) is expected to be pathogenic in the context of congenital amegakaryocytic thrombocytopenia. This variant is predicted to lead to an abnormal or absent protein product due to the creation of a premature termination codon in MPL, a gene where loss-of-function variants are known to be pathogenic. Please note: this variant was assessed in the context of healthy population screening.
