Background: Bladder cancer (BCa) is one of the most common cancer diagnosed worldwide with
multiple risk factors.
Aims: this study aimed to investigate the association between two single nucleotide polymorphisms
(SNPs) in the toll-like receptor 4 (Tlr4) gene (Asp299Gly and Thr399Ile) and the incidence of BCa.
Subjects and Methods: A total of 48 BCa patients and 36 healthy controls were enrolled in this study.
DNA was extracted from the blood samples taken from these participants. Tlr4 gene was amplified
with polymerase chain reaction (PCR) using specific primers. Genotyping of the SNPs of interest was
done by restriction fragment length polymorphism (RFLP).
Results: Overall, there were no significant association of BCa with neither SNPs, however, the mutant
allele (G) of the SNP Asp299Gly had higher frequency among patients compared with control
(P=0.05).
Conclusion: allele G of the SNP Asp299Gly may be considered as a risk factor for BCa
