title: Rapid single-step methods for detection of two immune defence gene polymorphisms: the myeloperoxidase (MPO) G-129A and the Fc gamma receptor 2A (FCGR2A) H/R131.
abstract: Polymorphisms of immune defence genes may act as disease modifiers and are studied by many researchers. A conclusive analysis of the impact of genetic variations typically requires a large number of sample specimens, and in retrospective studies this may include samples of reduced quality, e.g. formalin-fixed paraffin-embedded tissue specimens. Here we describe two new single-step methods for rapid and sensitive analysis of: 1. The G-129A myeloperoxidase (MPO) promoter polymorphism, which affects the amount of myeloperoxidase in neutrophils. 2. The Fc gamma receptor 2A (FCGR2A)-H/R131 polymorphism, which is critical to the binding of IgG2 immune complexes to phagocytes.
