MC3R and tuberculosis: When compared with other types of diagnostic tests for the diagnosis of TB, this MC3R gene expression test can show the genetic contribution of TB in a larger population, because this MC3R is a receptor that is widely expressed in the brain and various peripheral tissues and has been shown to contribute to many biological systems, especially in energy homeostasis, immunity, and inflammation, so the results are more accurate when used to map the genetics of TB in larger samples or populations.
