Houge-Janssens syndrome (HJS) is PP2A-related neurodevelopmental disorder. PP2A enzymes play essential regulatory roles in cellular signalling and physiology, including in brain function and development. It has been known for decades that PP2A dysregulation results in neurodegenerative disorders in the aging brain. Recently, It has been reported that mutations in several PP2A subunits cause rare neurodevelopmental disorders, such as NEDLBA and autosomal dominant intellectual developmental disorders (MRD).

Description
Intellectual developmental disorder, formerly known as Mental retardation (MR), is a neurodevelopmental disorder characterized by low intelligence quotient (IQ) and deficits in adaptive behaviors. Most causative genes identified so far are either located on the X chromosome or are associated with an autosomal recessive mode of inheritance. Recently, a lot of genes associated with autosomal dominant mental retardation have been identified.
