Testing the 44 variants in longitudinal data (up to 50,000 individuals), we observe significant effects on change for obesity traits (near APOE, TMEM18, TFAP2B) and pulse pressure (near FBN1, IGFBP3; known for implication in arterial stiffness processes). This evidence concerns the gene IGFBP3 and obesity due to melanocortin 4 receptor deficiency.
