Cell membrane diseases are life-threatening disorders that are genetic in nature and they usually work against proteins in our body that are key to ion channels and various receptors within the membrane. Process by which substances move from a higher concentration of that substance to a lower concentration of that substance. All cells have cell membranes.

The cell membrane also known as the plasma membrane PM or cytoplasmic membrane and historically referred to as the plasmalemma is a biological membrane that separates the interior of all cells from the outside environment the extracellular space which protects the cell from its environment. These diseases work by either disrupting the normal functions of the cells or by simply affecting the cell membrane.
