Genes affected

PPM1K (HGNC:25415): (protein phosphatase, Mg2+/Mn2+ dependent 1K) This gene encodes a member of the PPM family of Mn2+/Mg2+-dependent protein phosphatases. The encoded protein, essential for cell survival and development, is targeted to the mitochondria where it plays a key role in regulation of the mitochondrial permeability transition pore.
