Weighted Genetic Risk Scores and Prediction of Weight Gain in Solid Organ Transplant Populations.

When stratified by the median of age (w-GRS*age p = 0.001 and p = 0.02 for SNP group#1 and #2, respectively) individuals older than 54 years old had 0.23 BMI unit increase per additional risk allele and an explained BMI variability of 2.74% whereas those at 54 years or younger showed a trend of 0.10 units increase and 0.56% of explained BMI variability after multiple test correction (p = 0.08).
