A recent study, carried out through an integrative analysis of MM and normal BM specimens in two published datasets, showed that FABP5 mRNA expression was significantly correlated with the infiltrations of immune cells, such as B cell naïve, macrophages M1, macrophages M2, neutrophils, activated NK cells and resting memory T cells, in the BMM of MM patients. The gene discussed is FABP5; the disease is Miyoshi myopathy.
