WebJan 28, 2024 · In 1993, somatic mutations in PIGA gene were identified as the cause of PNH ( 4 – 6, 19 – 21 ). Although over 20 distinct enzymes are required to produce mature GPI anchors ( Figure 1 ), PIGA is the only gene in this pathway located on the X chromosome. WebSubsequent investigations have clarified much of the pathogenesis of the disease, including the genetic defect and the mechanism of complement-mediated hemolysis. This topic discusses the pathogenesis of PNH. The clinical manifestations, diagnosis, and treatment of PNH are presented in detail separately.
