Alignment of the sequence used for genotyping on the FGF21 gene. (A) The sequence used for genotyping the samples fro FGF21 rs838145 is marked (marker 1 and 2), the FGF21 rs838145 G/A SNP location is shown. The SNP is located close to the Izumo sperm-egg fusion 1 (IZUMO1) protein-coding region. (B) The sequence used for genotyping for the FGF21 rs838133 is marked (marker 3 and 4), the FGF21 rs838133 A/G SNP location is shown. The SNP is located on exon 2 of the FGF-21 gene. (C) Mapping of the FGF21 rs838145 and rs838133 location on chromosome 19.
