Recent examples of confirmed sex-differentiated effects identified through human GWAS include schizophrenia with SNPs in RELN [Shifman et al., 2008], serum uric acid concentrations with SNPs in SLC2A9 [Döring et al., 2008], and waist-hip ratio with SNPs in LYPLAL1 [Lindgren et al., 2009]. Here, RELN is linked to schizophrenia.
