Hailey-Hailey disease is a rare, inherited condition characterized by patches of blisters appearing mainly in the skin folds of the arm pits, groin and under the breasts. It is caused by a mutation in the gene that codes for a specific protein involved in the transportation of calcium and manganese ions from the cell cytoplasm and into a sac-like organelle called the Golgi apparatus.
