Mutations within the Piga gene in patients with paroxysmal nocturnal hemoglobinuria.
Blood 1994 May 2
Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired clonal hematologic disorder with multiple and varied clinical manifestations. The biochemical defect in PNH resides in the incomplete enzymatic assembly of glycosylphosphatidylinositol (GPI) anchors used for surface protein attachment. In all patients tested thus far, the defect is at the level of N-acetylglucosamine attachment to phosphatidylinositol (complementation class A defect). A human cDNA, Piga, that repairs cell lines with the class A defect has been recently cloned, making Piga a candidate gene for PNH. In the current study, using highly purified GPI-deficient granulocytes, we have performed Northern blot and reverse transcriptase polymerase chain reaction (RT-PCR) analysis of Piga in four patients with PNH. In each case, we have identified a mutation in the Piga coding sequence: three frameshift mutations were found, and a single nucleotide substitution (missense) mutation was identified. Our results provide convincing evidence that alterations in the Piga gene are responsible for PNH.
