Gel electrophoresis showing PCR- RFLP analysis of MTHFR, C677T locus; rs1801133. Detection of C677T polymorphism after HinfI digestion: fragments in lanes 1, 5, and 10 (171bp, 74 bp) indicate homozygote (CC) genotype; 3,4, 6, 7, 8, and 9 (245 bp) lanes 1, 5 and 10 showing a single band (245 bp) of undigested PCR product indicates homozygote (TT) genotype; lanes 2,and 11 heterozygote (C/T) genotype (245, 171 and 74 bp).
