HKDC1 and gestational diabetes: In contrast to the other GDM loci reported in this investigation, the lead SNV at the HKDC1 locus (rs9663238) demonstrates only weak statistical evidence of T2D association in previously reported trans-ancestry GWAS meta-analyses from the DIAMANTE Consortium (16) (P = 0.0083, compared with P < 10−65 at the other four loci).
