MEFV (Mediterranean fever) is a human gene that provides instructions for making a protein called pyrin (also known as marenostrin). Pyrin is produced in certain white blood cells (neutrophils eosinophils and monocytes) that play a role in inflammation and in fighting infection. Inside these white blood cells pyrin is found with the cytoskeleton the structural framework that helps to define the shape size and movement of a cell.
