<unk>  (KTS), also called Amelo-cerebro-hypohidrotic syndrome is a rare inherited syndrome characterized by epilepsy, psychomotor delay or regression, intellectual disability, and yellow teeth caused by amelogenesis imperfecta (abnormal formation of tooth enamel). It is a type A ectodermal dysplasia. It is autosomal recessive and symptoms appear in early childhood. The syndrome was first described in 1974 by Alfried<unk>  and colleagues. Only 24 affected individuals are known as of 2012. The disease has not been connected to any other known epileptic syndromes. Some but not all cases are associated with mutations in a gene called ROGDI. Another gene that has been associated with this condition is the SLC13A5 gene Diagnoses of this syndrome have occurred in Switzerland, Sicily, the Northern Israel Druze community as well as some other parts of Western Europe.
