Background: Leprosy (Hansen's disease) is a chronic, debilitating disease predominantly of the peripheral nervous system characterized by the impairment of peripheral nerves and subsequent sensory loss caused by . The pro- and antiinflammatory cytokine genes play a major role in nerve damage in leprosy.

Aims and Objectives: The objective of the present study is to ascertain the association of cytokine gene polymorphisms TNFα - 308G/A (rs 1800629), IFNγ +874A/T (rs 2430561), and IL10 - 1082G/A rs 1800896 in causation with leprosy.

Materials and Methods: The present study comprised 365 leprosy patients and 185 control subjects. The polymorphisms in TNFα-308, IFNγ+874, and IL10-1082 genes were typed using the amplification refractory mutation system polymerase chain reaction method (ARMS PCR).

Results: The present study found significant association between IL10-1082 GA heterozygote ( < 0.02) and IFNγ+874 AA ( < 0.001) genotype and leprosy. TNFα-308GA could not establish any association with the disease.

Conclusion: The identification of genetic variations in pro- and antiinflammatory cytokines that are susceptible to leprosy would assist in better understanding of the pathogenesis of leprosy and perhaps lead to new approaches for diagnosis and treatment.
