<unk>  is first described in 2003 by<unk>  Z. et al. as an autosomal recessively inherited disorder in a Turkish family. It is characterized by mainly gastrointestinal hypomotilily related to visceral neuromyopathy which cause chronic intestinal pseudo-obstruction (CIIP). CIIP is a rare and severe clinical syndrome characterized by symptoms and signs of intestinal occlusion, in the absence of any mechanical obstruction. Family members of this syndrome had also mega duodenum, Barrett's esophagus, different cardiac abnormalities and some other organ involvement. In 2007 Deglincerti A et al. studied genetic abnormalities in this family members and identified a new syndromic locus on chromosome 8q23-q24.
