Interestingly, other loci identified by SNPs for BMI and/or body fat distribution in the current study are involved in the immune system, too (Supplementary Table S8): ITIH4 (Murakami et al., 2015; locus 5, 3p21.1; BP, schizophrenia), SLC39A8 (Liu et al., 2013b; locus 9, 4q24; schizophrenia, intelligence), and HLA-DRB1 (Arango et al., 2017; locus 34, 6p21.32; schizophrenia). The gene discussed is SLC39A8; the disease is schizophrenia.
