The HLA-DRB1*13/DRB3/DQB1*06 haplotype is preferentially transmitted to Brazilian patients with paracoccidioidomycosis, with a 20% TDT transmission rate (p = 0.013; RR = 5.0).
- Why it matters: Identifying HLA Class II variants linked to paracoccidioidomycosis susceptibility addresses the gap in understanding which immune-genetic backgrounds increase risk in endemic disease.
- What they did: In 30 Brazilian family trios, HLA-DRB1 and DQB1 were typed by PCR-SSP and tested with TDT and FBAT; four haplotype carriers were further assessed using gp43-stimulated cytokine assays.
- The result: The haplotype showed association with PCM (FBAT Z = +2.67) and, after gp43 stimulation, carriers had a lower IFN-γ/IL-10 ratio (p = 0.027; Bayes factor = 2.82), implying altered Th1 polarization.
