Abstract excerpt
Familial aggregation, high relative risk to siblings, and segregation analysis, suggest genetic control of visceral leishmaniasis in Brazil. Class II gene effects in mice, and high circulating tumour necrosis factor alpha in humans, provide reasons to target HLA. Fifteen polymorphic markers across 1.03 Mb (DQB1 to TNFa) were genotyped (87 multicase families; 638 individuals). Model-based parametric analyses using...
