The RASSF1 and GPM6A genes were selected for this study based on the findings of genome-wide association study (GWAS), which revealed rs2073499 (A/G) and rs13142920 (A/C) polymorphisms in these genes, respectively, which were found to be associated with schizophrenia and had a MAF < 10% in East Asian population (12, 17–18).
