Comparably, there is an association between 5‐HT2A gene mutation and waist circumference (Halder et al., 2007; Rosmond et al., 2002), and between 5‐HT2A gene mutation and presence of heart disease, stroke, and diabetes (Halder et al., 2007; Kring et al., 2009). The gene discussed is HTR2A; the disease is heart disorder.
