title: Study of KIR genes in Lebanese patients with tuberculosis.
abstract: A total of 103 Lebanese tuberculosis (TB) cases and 38 controls without TB were studied for the killer cell immunoglobulin-like receptors (KIR) genotypic profile using polymerase chain reaction sequence-specific primers. Patients and controls were assigned to the AA, AB or BB genotypes based on their A or B haplotype genetic make-up, and KIR gene frequencies were compared. We found an increase in the KIR A haplotype in TB patients compared to controls, and only KIR 2DL3 was found to be significantly more prevalent among TB patients. This confirms the findings of another unique international study performed in the Mexican population showing a greater repertoire of inhibitory KIR genes among TB patients than controls.
