This is important since it has been established that ATP7A60, fibrinogen chain beta (FGB)61, fibrinogen chain alpha (FGA)62, Solute carrier family 11 member 2 (SLC11A2)58, and Solute carrier family 40 member 1 (SLC40A1)63 might have essential roles in the pathogenesis of T2DM. This evidence concerns the gene SLC40A1 and type 2 diabetes mellitus.
