ZDHHC4 and anorexia nervosa: DC1 showed a significant negative genetic correlation with anorexia nervosa (rg = −0.18, s.e. = 0.03, p = 5.02 × 10−08) and positive genetic correlations with waist circumference (rg = 0.14, s.e. = 0.03, p = 3.8 × 10−06) and waist-to-hip-ratio (rg = 0.14, s.e. = 0.03, p = 5.13 × 10−06) (Fig. 3).
