The results in Tables 2, 3, 4 showed that the strength of GABRB2 association significantly segregated with the patient subgroups having the more severe psychosis symptoms (for example, p = 0.001–0.003 vs. p = 0.232–0.569 for pairwise haplotypes in the patient subgroup with high PANSS scores vs. subgroup with low PANSS scores), and the association was due to increased frequencies of minor alleles in these patient subgroups relative to control (Figures 4 and 5). The gene discussed is GABRB2; the disease is psychotic disorder.
