The PARK2_e01(-697) Polymorphism does not Associate with Susceptibil-ity to Typhoid in Punjabi Population, Pakistan: A Case Control Study

Background: SNP based association studies have revolutionized the field of biomed-icines. Enteric fever is a systemic disease with etiologic agents Salmonella enterica serovar typhi and paratyphi. It is a serious health issue worldwide and presents wide variations in incidence, rates, and severity. Previous investigations have revealed that genetic variations may lead to sus-ceptibility to typhoid fever. A current study was performed to investigate the potential association of PARK2_e01(-697) polymorphism with the susceptibility to typhoid in the Punjabi population.

Methods: For this case-control study, blood samples obtained from typhoid patients with positive Typhidot or blood culture test (n=72) and healthy controls (n=73) were processed for DNA ex-traction. The polymorphism PARK2_e01(-697) analysis was carried out by using PCR and RFLP.

Results: No allelic association was found between PARK2_e01(-697) and susceptibility to ty-phoid fever in the understudy population.

Conclusion: This case control study is the demonstration of the non-association of PARK2_e01(-697) with typhoid in the Pakistani population. Future research, using a larger population size, will help to elucidate the role of PARK2_e01(-697) polymorphism in typhoid pathogenesis.
