Abstract |
Human protection of telomeres 1 (POT1) gene is a single stranded telomere binding proteins with a critical role in ensuring chromosome stability. There have been variants of POT1 gene, and the polymorphisms of POT1 gene were associated with some diseases. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) is a traditional method to detect the single nucleotide polymorphism (SNP), and it can be used to detect the polymorphism of rs10250202. But the restriction enzymes required for the detection of the polymorphism of rs10250202 are expensive. So we designed a novel PCR-RFLP assay for genotyping the POT1 rs10250202 SNP. In the study, a new restriction enzyme cutting site was created by created restriction site PCR (CRS-PCR), and the restriction enzyme BclI for CRS-PCR was cheaper than other enzymes. After detecting Han Chinese workers, Allele frequencies were found to be 51.54 % for allele A and 48.46 % for allele C respectively. The PCR results were confirmed by DNA sequencing. CRS-PCR provides a simple, low-cost, practical, and reproducible method. |
