DRD4 and Abdominal obesity: Likewise, for W, we found that patients with one or two DRD4-L variants in DRD4-VNTR or 9R9R homozygous in DAT1-VNTR had a higher risk of abdominal obesity than carriers of two DRD4-S variants (Figure 1c, X2: 3.76, df: 1, p = 0.052, OR: 1.67 [1.02–2.74]) and 10R10R homozygotes in DAT1-VNTR (Figure 1d, X2: 6.05, df: 2, p = 0.049, OR: 2.77 [1.20–6.36]).
