In females, both genotypes of CLOCK rs9312661 in the VLFC showed an increased incidence of abdominal obesity compared with the reference group (AA genotype, OR: 2.26, 95% CI: 1.43–3.56, p = 0.0005; GA/GG genotype, OR: 2.11, 95% CI: 1.38–3.23, p = 0.0005). The gene discussed is CLOCK; the disease is Abdominal obesity.
