Genome-wide interactions with dairy intake for body mass index in adults of European descent. Molecular Nutrition and Food Research. https://doi.org/10.1002/mnfr.201700347. DOI: https://doi.org/10.1002/mnfr.201700347 Interpretive Summary: Obesity is a product of genetic and dietary factors, and among the dietary factors, certain food groups have been shown to modify obesity risk. In particular, dairy products have been reported to be associated with increases, decreases or neutral effects on body weight. We hypothesized that genetic factors contribute to differences in how foods affect body mass index (BMI) in different people. To investigate this hypothesis, we examined relationships between dairy products of different forms (low fat, high fat and total) and genetic variants across the whole genome. When we combined results from analysis in 9 studies (up to 25,513 individuals of European descent, living in Europe or the US), we identified six genetic sites that affected people's BMI in the context of dairy food intake. In other words, depending on the presence or absence or these variants, BMI may be higher or lower with greater intake of dairy foods. In order to strengthen this evidence of a gene-diet interaction, we then evaluated the same six variants in a set of four new cohort studies, totaling up to 17,675 European and Australian people. Of the six genetic variants, one showed a similar interaction in the new cohorts in that the presence of the variant was associated with lower BMI in people who consumed more dairy products. These findings increase our understanding of how genetics and diet act together to promote or prevent weight gain and may eventually have implications for dietary recommendations that make use of genetic information. Technical Abstract: Scope: Body weight responds variably to the intake of dairy foods. Genetic variation may contribute to inter-individual variability in associations between body weight and dairy consumption. Methods and results: We conducted a genome-wide interaction study to discover genetic variants that account for variation in BMI in the context of low-fat, high-fat and total dairy intake in cross-sectional analysis. Data from 9 discovery studies (up to 25,513 European descent individuals) were meta-analyzed. Twenty-six genetic variants reached the selected significance threshold (P-interaction <10^-7), and six independent variants (LINC01512-rs7751666, PALM2/AKAP2-rs914359, ACTA2-rs1388, PPP1R12A-rs7961195, LINC00333-rs9635058, AC098847.1-rs1791355) were evaluated meta-analytically for replication of interaction in up to 17,675 individuals. Variant rs9635058 (128 kb 3' of LINC00333) was replicated (P-interaction =0.004). In the discovery cohorts, rs9635058 interacted with dairy (P-interaction=7.36 x 10^-8) such that each serving of low-fat dairy was associated with 0.225 kg/m2 lower BMI per each additional copy of the effect allele (A). A second genetic variant (ACTA2-rs1388) approached interaction replication significance for low-fat dairy exposure. Conclusions: Body weight responses to dairy intake may be modified by genotype, in that greater dairy intake may protect a genetic subgroup from higher body weight. |
