Although extrapulmonary organs are involved in 20% of patients with tuberculosis, the host genetic factors associated with the extrapulmonary dissemination of tuberculosis are not yet known. The aim of this study was to identify the host genetic factors associated with the extrapulmonary dissemination of tuberculosis by comparing gene expression profiles of patients who had recovered from extrapulmonary tuberculosis and those who had recovered from pulmonary tuberculosis.
