Figure 1

Genotyping of GCKR rs780093 using Tm-shift method. GG genotype has higher Tm value, namely, the 5′ end to join long sequences of alleles homozygous. AA genotype has lower Tm value, namely, the 5′ end to join short sequences of alleles homozygous. AG has the mixed curves with low and high Tm values.
