Resumo: Introduction: Papillary thyroid cancer corresponds to approximately 1% of all carcinomas; nevertheless, it is the most prevalent endocrine neoplasm in the world. Studies reveal that the BAX (−248 G > A) polymorphism may be associated with negative regulation of BAX gene transcription activity, causing a decrease in its protein expression. Objective: The present study aimed to describe the genotype and allele frequencies of BAX single nucleotide polymorphisms (−248 G > A) (rs4645878) in the research patients, and to associate its presence with susceptibility to papillary thyroid cancer. Methods: This case-control study was conducted with 30 patients with papillary thyroid cancer. For the evaluation of genetic polymorphisms, the polymerase chain reaction-restriction fragment length polymorphism technique was employed. Allele and genotype frequencies were estimated using the SPSS program, and significant associations were considered when p < 0.05. Results: There was a significant genotypic difference between papillary thyroid cancer and the control group (p = 0.042). The GG genotype provided a protective factor for papillary thyroid cancer (p = 0.012, odds ratio (OR) = 0.313; confidence inter- val (CI) = 0.123–0.794). Likewise the G allele was a protective factor for papillary thyroid cancer (p = 0.009; OR = 0.360; CI = 0.163–0.793). The BAX gene polymorphism (−248 G > A) was associated with papillary thyroid cancer. Conclusion: BAX (−248 G > A) GG genotype carriers, or at least one mutated allele, was associated with papillary thyroid cancer in the Brazilian population studied, and the G allele presence is considered a protective factor against papillary thyroid cancer occurrence.
