Designing and Validation of One-Step T-ARMS-PCR for Genotyping the rs1799983 SNP.

The transversion of G to T (G894T) in human endothelial nitric oxide synthase () gene has profound effects such as male infertility, recurrent miscarriage, multiple sclerosis and cardiovascular diseases. Development of a new Multiplex Tetra-Primer Amplification Refractory Mutation System - Polymerase Chain Reaction (T-ARMS-PCR) for detection of rs1799983 (G894T) in the human was sought. A T-ARMS-PCR for rs1799983 polymorphism in a single-step PCR was carried out, and the results were confirmed by PCR-RFLP technique in 82 infertile men with varicocele. The results showed that GG (varicocele infertile men), GT and TT genotypes appear to be 53.65%, 34.14%, and 12.19%, respectively. Full accordance between PCR-RFLP and T-ARMS-PCR methods for genotyping of rs1799983 polymorphism was found. This is the first work that describes a rapid, relatively cheap, high throughput detection of G894T polymorphism in that can be used in large scale clinical studies.
