OBJECTIVES: Azathioprine (AZA) is an effective immunosuppressant commonly used for malignancy and immune-mediated disorders. The association between genetic polymorphisms and AZA-induced adverse effects has not been elucidated. Hence this study aimed to evaluate the relationship between single nucleotide polymorphisms of ITPA (C94A) with azathioprine-induced adverse effects.
METHODS: A cross-sectional study was performed on 120 patients who were on AZA therapy for immunobullous disorders and inflammatory bowel disease (IBD). Eligible patients were enrolled from outpatient Departments of dermatology and medical gastroenterology and five mL of blood was collected after obtaining written informed consent. DNA extraction and genotyping were done by phenol-chloroform method and real-time polymerase chain reaction (RT-PCR), respectively.
RESULTS: The minor allele frequency of ITPA (A allele) was 30.8 %. The mutant genotypes of ITPA (C94A) were found to have no significant association with overall adverse effects in the South Indian patients on AZA therapy.
CONCLUSIONS: We report no significant association between ITPA rs1127354 genetic polymorphism and adverse effects in the South Indian patients on AZA therapy.
