In genome-wide association studies (GWAS), single-nucleotide polymorphisms (SNPs) around IGF1 have been associated with height [24]–[26] and the C allele of rs35767 upstream of the gene has been associated with increased fasting insulin and insulin resistance risk [27] as well as lower levels of IGF-I [28]–[30]. Here, IGF1 is linked to Insulin resistance.
