The T minor allele of the REV-ERB-α rs2071427 polymorphism is associated with a higher BMI [238] while minor allele carriers for the REV-ERB-α rs2314339 polymorphism have a lower probability of abdominal obesity than non-carriers, as they have lower obesity parameters and lower waist circumference values. This evidence concerns the gene NR1D1 and Abdominal obesity.
