Identification of Associations Between Genetic Factors and Asthma that are Modified by Obesity
Abstract
We performed a genome-wide gene by environment (asthma) interaction analysis for the outcome of body mass index (BMI) in the Multi-Ethnic Study of Atherosclerosis (MESA) (N=2474 Caucasians, 257 asthmatics) and replicated findings in the Framingham Heart Study (FHS) offspring cohort (N=1408 Caucasians, 382 asthmatics). The replicable tagging single nucleotide polymorphism (SNP) rs2107212 was further examined in stratified analyses. Seven SNPs clustered in 17q21.2 were identified to be associated with higher BMI among asthmatics (interaction p < 5 10-7 in MESA and p < 0.05 in FHS). Nominally associated copy number variations interacting with BMI were associated with asthma among African American women in the Womens Health Initiative study.
