SNPs for schizophrenia include dopamine receptor D2 gene (DRD2), calcium voltage‐gated channel auxiliary subunit beta 2 gene (CACNB2), and glutamate metabotropic receptor 3 gene (GRM.3)40 Obtained results present 10 SNP‐disease combinations related to the DRD2 (Figure 4J), 45 related to the CACNB2 (Figure 4K), and 16 related to the GRM3 (Figure 4L). This evidence concerns the gene DRD2 and schizophrenia.
