Brachydactyly mental retardation syndrome (BDMR), also known as Albright hereditary osteodystrophy-like syndrome, is a complex disorder characterized by brachydactyly and mental retardation including autism spectrum disorder. It has been confirmed that this disease is associated with some deletions of 2q37. Individuals with BDMR and Smith-Magenis syndrome (SMS) have very similar features. Mutation of the BDMR-causative gene HDAC4 results in reduced expression of RAI1, whose haploinsufficiency leads to SMS.
