Abstract
Locus-specific amplicon sequencing was used to HLA type 336 participants of Maasai ethnicity at the HLA-A, -B, -C, -DRB1, -DQB1 and -DPB1 loci. Participants were recruited from three study villages in North Tanzania, for the purpose of investigating risk factors for trachomatous scarring in children. Other than HLA-A, all loci significantly deviated from Hardy-Weinberg equilibrium, possibly due to high relatedness between individuals: 238 individuals shared a house with at least one another participant. The most frequent allele for each locus were A*68:02 (14.3 %), B*53:01 (8.4 %), C*06:02 (19.2 %), DRB1*13:02 (17.7 %), DQB1*02:01 (16.9 %) and DPB1*01:01 (15.7 %), while the most common inferred haplotype was A*68:02 ∼ B*18:01 ∼ C*07:04 ∼ DRB1*08:04 ∼ DQB1*04:02 ∼ DPB1*04:01 (1.3 %).
