Hirschsprung's disease as a neurochristopathy.

Recent molecular-genetic and histochemical studies of intestinal aganglionosis have confirmed the initial classification established by Bolande, who considered Hirschsprung's disease (HD) a neurocristopathy. This paper is a critical review of the results of molecular-genetic studies carried out from 1992 to date. In particular, the author focuses on the possible clinical impact of the identification of RET as a causative gene for HD.
