Introduction: To investigate susceptibility to leprosy reactions, three polymorphisms of the natural resistance-associated macrophage protein (NRAMP1) gene were determined in 201 individuals who were attended at two reference centers in Recife, between 2007 and 2008. Of these, 100 were paucibacillary and 101 were multibacillary.
Methods: The 274C/T, D543N and 1729+55del4 polymorphisms of the NRAMP1 gene were determined using the technique of restriction fragment polymorphism on DNA extracted from peripheral blood.
