GIPR and Insulin resistance: Of 6 loci previously associated with insulin resistance, here 3 also showed an association with HOMA2-IR and a trend towards significance for GDM2013 but not GDM1999 including SNPs rs7607980 in the COBLL1 gene [40], rs13389219 near GRB14 and rs10423928 in the GIPR gene indicating that some of the genetic basis seem to be driven by previously reported insulin resistance loci.
