A cause of mental retardation, autism discovered

The term intellectual disability covers a large number of clinical entities, some with known cause and others of uncertain origin. For example Down syndrome is due to an extra copy of chromosome 21 and Rett syndrome is in part caused by a mutation in the control switch gene called MeCP2. In other cases the mechanisms by which they are produced are not clearly identified. Now a research team has discovered a mechanism that identifies a cause of intellectual disabilities in these puzzling cases.
