Tourette syndrome

An autosomal dominant disorder (OMIM:137580) appearing in childhood that is characterised by multiple motor and vocal tics present for more than 1 year; obsessive-compulsive behaviour, attention-deficit disorder, coprolalia, echolalia, and other psychiatric disorders may occur.
Molecular pathology
Defects of SLITRK, which encodes an integral membrane protein involved in neurite outgrowth, have been linked to Tourette syndrome.
