Different populations existed in one study. HWE, Hardy-Weinberg equilibrium. PB, population-based; HB, hospital-based. FLUPD, fluorescent-labeled universal primer; PCR, polymerase chain reaction; SSCP, single-strand conformation polymorphism; RFLP, restriction fragment length polymorphism; MALDI-TOF, matrix assisted laser desorption/ionization time-of-flight.
