Genetic Association Between TFRC Gene Polymorphism (rs11915082 and rs3817672) and Susceptibility to Oral Premalignant Disorder in South Indian Cohort
摘要
To investigate the association of the TFRC promoter variant rs11915082 and the missense variant rs3817672 with precancerous oral lesions. A comparative study included 300 participants: 100 with OSMF, 100 with leukoplakia, and 100 healthy controls. Genotyping was conducted using PCR-RFLP to analyze the association of SNP genotypes and allele frequencies with the diseases. Smokers showed higher prevalence rates of OSMF (72%) and leukoplakia (62%) compared to healthy controls (48%), with tobacco chewers also exhibiting elevated rates of OSMF (59%) and leukoplakia (61%). Chewing and smoking habits showed significant risk for oral potentially malignant disorders. The rs11915082 variant showed AA genotype distributions of 19% in OSMF and 31% in leukoplakia, while the TT genotype of rs3817672 was more prevalent in OSMF (41%) than in leukoplakia (21%). Although the AA genotype had insignificant odds ratios, the TT genotype had significant associations (ORs 9.46 and 3.0) and T allele were significantly higher p < 0.001 in OSMF and leukoplakia, suggesting a genetic predisposition to these disorders. TFRC rs11915082 polymorphism was not significantly associated with OSMF or leukoplakia in the South Indian cohort, while the missense variant rs3817672 could be a valuable therapeutic marker for assessing oral premalignancy prognosis.
