Effects of loss-of-function and gain-of-function mutations of c-kit on the gastrointestinal tract.

Abstract excerpt

Protooncogene c-kit encodes a receptor tyrosine kinase, KIT. Interstitial cells of Cajal (ICCs) that are important for the autonomous movement of the gastrointestinal tract essentially require the normal function of the KIT for their development. Therefore, germline loss-of-function mutations of the c-kit gene cause deficiency of ICCs that results in disturbed gastrointestinal movement. On the other hand, somatic...
