Identification of ITPA on chromosome 20 as a susceptibility gene for young-onset tuberculosis.

ABSTRACT: Tuberculosis (TB) is a complex disease, and both genetic and environmental factors contribute to disease progression. A previous genome-wide linkage study in Thailand determined that chromosome 20p13-12.3 may contain risk factors for young-onset disease. The present study aimed to identify novel susceptibility genes for young-onset TB within a 1-Mbp target region adjacent to the top-ranking risk marker in Chr.20p13-12.3. We performed next-generation sequencing (NGS) of the region in 13 young patients from multi-case families in Thailand. We then selected the functionally interesting single-nucleotide polymorphisms as candidates for subsequent analyses. The detected candidates rs13830 and rs1127354 in ITPA showed an association with young (<45 years old) TB patients. However, there was no a
