XRCC5 VNTR, XRCC6 -61C>G, and XRCC7 6721G>T Gene Polymorphisms Associated with Male Infertility Risk: Evidences from Case-Control and In Silico Studies

Figure 2

Schematic diagram and results of the PCR-RFLP products of XRCC6 and XRCC7: (a) schematic diagram of XRCC6 -61C>G, which showed BanI restriction enzyme site; (a′) polymorphism of PCR-RFLP products of the XRCC6 -61C>G gene in 1% agarose gel electrophoresis. Lane M: 50 bp DNA ladder; lane 1: CC homozygous genotype; lane 2: CG heterozygous genotype; lane 3: GG homozygous genotype; (b) schematic diagram of XRCC7 6721G>T which showed PvuII restriction enzyme site; (b′) polymorphism of PCR-RFLP products of the XRCC7 6721G>T gene in 1% agarose gel electrophoresis, lane M: 50 bp DNA ladder; lane 1: GG homozygous genotype; lane 2: GT heterozygous genotype; lane 3: TT homozygous genotype.
