In parallel, we also measured regional brain … WebJun 1, 2016 · Background. The dopamine D 2 receptor (D 2 R) has received much attention in obesity studies. Data indicate that D 2 R is reduced in obesity and that the TaqA1 D 2 R variant may be more prevalent among obese persons. It is often suggested that reduced D 2 R generates a reward deficiency and altered appetitive motivation that induces …
WebBackground: In adults, the Taq1a polymorphism (rs1800497) near the D2 receptor (DRD2) gene is associated with body mass index and binge eating and is more prevalent among non-Hispanic Blacks (NHB) and Hispanic-Americans (HA) relative to non-Hispanic Whites (NHW).
