Mutational analysis ofRET/GDNF/NTN genes in children with total colonic aganglionosis with small bowel involvement

Abstract excerpt

Hirschsprung disease (HSCR) is characterized by the absence of intramural ganglion cells in the distal gut, resulting in bowel obstruction shortly after birth. Aganglionosis usually affects the distal colon, but may also extensively involve the entire colon and, rarely, the more proximal bowel. Recently, germline mutations of RET, GDNF, and NTN genes have been reported in HSCR. Here we describe the results of...
