In this particular cohort, the associated region was delimited by microsatellites CZM004– COR112 (36.11–36.71 Mb of chromosome 20 in TB-T2T genome), covering approximately a 0.6 Mb of chromosome 20, and containing expressed genes (DRA, DRB, DQA, DQB), pseudogenes, microsatellites, and RNA non coding sequences (lncRNA, microRNA). The gene discussed is SLC26A3; the disease is tuberculosis.
