In this study, the rs1801275 SNP was analyzed using Sanger sequencing. The presence of a single peak denoted explicitly as ‘A’ is suggestive of an individual possessing a homozygous allele for the A gene. The presence of a single ‘G’ peak is indicative of a homozygous allele for the G variant. The presence of both the ‘A’ and ‘G’ peaks is indicative of the presence of an A/C heterozygous allele.
