The overlap between the minimal nine gene set for TB vs. LTBI and the robust ten gene set consisted of three genes (HBD, CHRM2 and GLDC) and the overlap between the minimal 42 gene set for TB vs. LTBI vs. HC and the robust ten gene set consisted of seven genes (HBD, CHRM2, GLDC, ACOT7, SNX17, TAS2R46 and PIGC). This evidence concerns the gene PIGC and tuberculosis.
