The combination of single nucleotide polymorphisms rs6720173 (ABCG5), rs3808607 (CYP7A1), and rs760241 (DHCR7) is associated with differing serum cholesterol responses to dairy consumption.

Existing evidence on the influence of genetic architecture on serum cholesterol responsiveness to dietary interventions focuses on individual single nucleotide polymorphisms and single nutrients. We associated the combination of ABCG5 rs6720173-C, CYP7A1 rs3808607-TT, and DHCR7 rs760241-GG genotypes with lower low-density lipoprotein cholesterol concentrations relative to the combination of rs6720173-GG, rs3808607-G, and rs760241-A genotypes (-0.37 ± 0.12 (n = 9) vs. +0.38 ± 0.14 mmol/L (n = 7), p = 0.0016) following a blended dairy (3 servings/day for 4 weeks) intervention.
