RET proto-oncogene in the development of human cancer. In contrast to HSCR, the pathologic findings include hyperplasia of enteric ganglia vs absent ganglion cells in HSCR and other features such as “giant ganglia” that many pathologists find controversial [ Kapur ].
Review Total colonic aganglionosis and Hirschsprung’s disease: In one family, cosegregation of the NF1 and megacolon phenotypes was associated with inheritance of both an abnormal NF1 allele from one parent and an abnormal GDNF allele from the other parent [ Bahuau et al ], thus reinforcing the role of multiple gene interactions in the development of HSCR.
An effort is generally made to resect a variable length of gut just proximal to the aganglionic zone since this transitional area may have altered pathologic properties e.
Usually signs and symptoms appear shortly after birth, but sometimes they’re not apparent until later in life. Resection of the aganglionic segment and anastomosis of proximal bowel to the anus “pull-through” is the standard treatment for HSCR.

Observing the Meissner and Auerbach plexus with hirschspdung techniques and enolase S, loss of neurons ganglion cells and lower density of such plexuses were observed with respect to a normal colon Figs. Most pathogenic variants are associated with nonsyndromic forms of HSCR; however, because a few individuals are reported to have other anomalies this form of HSCR may also be syndromic.
