Although both signatures clearly demonstrate specificity for the presence of TB, only 16 probes, corresponding to 15 genes, were common to both signatures (TMEM51, APOL6, STAT2, STAT1, LOC653610, GK, DHRS9, TRAFD1, UBE2L6, GBP2, LPCAT2, AK026751, ASPHD2, BRSK1, and FLVCR2). The gene discussed is STAT1; the disease is tuberculosis.
