Genes affected

PPP2CA (HGNC:9299): (protein phosphatase 2 catalytic subunit alpha) This gene encodes the phosphatase 2A catalytic subunit. Protein phosphatase 2A is one of the four major Ser/Thr phosphatases, and it is implicated in the negative control of cell growth and division. It consists of a common heteromeric core enzyme, which is composed of a catalytic subunit and a constant regulatory subunit, that associates with a variety of regulatory subunits. This gene encodes an alpha isoform of the catalytic subunit. [provided by RefSeq, Jul 2008]

PPP2CA Gene-Disease associations (from GenCC):

• Houge-Janssens syndrome 3
