| Abstract: | The region of conserved synteny on mouse chromosome 11/human 17q11-q21 is known to carry a susceptibility gene(s) for intramacrophage pathogens. The region is rich in candidates including NOS2A, CCL2/MCP-1, CCL3/MIP-1x, CCL4/mip-1b, CCL5/RANTES, CCR7, STAT3 and STAT5A/5B. To examine the region in man, we studied 92 multicase tuberculosis (627 individuals) and 72 multicase leprosy (372 individuals) families from Brazil. Multipoint nonparametric analysis (ALLEGRO) using 16 microsatallites shows two peaks of linkage for leprosy at D17S250 (Z score 2.34; P=0.01) and D17S1795 (Z 2.67; P=0.004) and a single peak for tuberculosis at D17S250 (Z 2.04; P=0.02). Combined analysis shows significant linkage genes contribute, 49 informative single nucleotide polymorphisms were typed in candidate genes. Family-based allelic associationtesting that was robust to family clustering demonstrated siginificant associations with tuberculosis susceptibility at four loci separated by intervals (NOS2A-8.4Mb-CCL18-32.3kb-CCL4-6.04 Mb-STAT5B) up to several Mb. Stepwise conditional logistic regression analysis using a case/pseudo-control data set showed that the four genes contributed separate main effects, consistent with a cluster of susceptibility genes across 17q11.2 (AU).
