  • Beschreibung: <p>A substantial proportion of subjects exposed to a contagious tuberculosis case display lack of tuberculin skin test (TST) reactivity. We previously mapped a major locus (TST1) controlling lack of TST reactivity in families from an area in South Africa where tuberculosis is hyperendemic. Here, we conducted a household tuberculosis contact study in a French area where the endemicity of tuberculosis is low. A genomewide analysis of TST negativity identified a significant linkage signal (P &lt; 3 × 10⁻⁵) in close vicinity of TST1. Combined analysis of the 2 samples increased evidence of linkage (P = 2.4 × 10⁻⁶), further implicating genetic factors located on 11pl4-15. This region overlaps the TNF1 locus controlling mycobacteria-driven tumor necrosis factor α production.</p>
