Abstract: TP53 gene encoding polymorphisms is a risk allele in terms of carcinogenesis. Here, we studied the risk assessment and association of TP53 to understand the cancer biology and behaviour in cervical cancer patients and possible anticancer drug development interfering with p53 protein production. TP53 gene encodes a central protein of apoptosis pathway p53 and its allelic variant has been postulated to play a vital role in carcinogenesis in addition to a variety of neurodegenerative disorders. We undertook a case control study, to examine the possible association of TP53 gene codon 72 polymorphism in leukocyte DNA from a total of 200 subjects (100 controls and 100 cases). TP53 codon Arg72Pro (rs1042522) genotype was identified using allele specific PCR and RFLP with statistical analysis using Vassar Stats (online). In Chhattisgarh population, individuals with GC and GG genotypes of TP53 gene codon 72 polymorphism has a significantly higher risk of cervical cancer (OR=6.36, 95%CI=2.8-14.03 and OR=7.42, 95%CI=3.5-15.9) as compared to CC genotype (OR=1) which was taken as reference. The 'G' allele was found to confer a significant risk of cervical cancer (OR= 3.69, 95%CI= 2.40-5.5) compared to 'C' allele. The present case control study demonstrated the prevalence of the Arg/Arg (GG) genotype in women with cervical cancer among Chhattisgarh population.
