The present study detected 9 single nucleotide polymorphisms (SNPs) at the PLA2G4C and PLA2G6 loci among 240 Chinese parent-offspring trios of Han descent. Of these 9 SNPs, 5 showed highly polymorphic in the Chinese population. They were then applied as genetic markers to test the genetic association of these two calcium-independent cytosolic PLA2 genes with schizophrenia. The transmission disequilibrium test (TDT) showed that rs1549637 at the PLA2G4C locus was the only SNP associated with the illness (chi(2) = 5.63, P = 0.018). The global P-value was 0.082 for 1000 permutations with the TDT analysis. Neither the conditional on allele test nor the conditional on genotype test showed a disease association for the combination of these two genes. Because the PLA2G4C association is so weak, this initial finding should be interpreted with caution.
