Insights
Hirschsprung's disease (HSCR) is a congenital condition where the enteric nervous system is absent in the distal gut. Understanding its genetic and developmental basis offers future hope for affected infants.
Area of Science:
- Developmental biology
- Gastroenterology
- Genetics
Background:
- Hirschsprung's disease (HSCR) involves the absence of the enteric nervous system in the distal bowel.
- Infants with HSCR typically present with bowel obstruction shortly after birth.
- Current surgical treatments for HSCR have variable long-term outcomes.
Purpose of the Study:
- To synthesize recent advances in understanding HSCR.
- To elucidate the developmental and molecular basis of Hirschsprung's disease.
- To explore future therapeutic applications for children with HSCR.
Main Methods:
- Review of recent scientific literature on HSCR.
- Analysis of genetic and molecular mechanisms underlying HSCR.
- Examination of normal enteric nervous system development and fetal motility.
Main Results:
- Significant progress has been made in identifying genes and molecular pathways involved in HSCR.
- Enhanced understanding of fetal gut development and motility has been achieved.
- The review integrates genetic, developmental, and clinical aspects of HSCR.
Conclusions:
- Knowledge of HSCR's developmental and biological underpinnings is rapidly advancing.
- This integrated understanding holds potential for improved future treatments for HSCR.
- Further research can translate biological insights into clinical benefits for affected children.
Abstract:
Hirschsprung's disease (HSCR) is characterized by absence of the enteric nervous system in a variable portion of the distal gut. Affected infants usually present in the days after birth with bowel obstruction. Despite surgical advances, long-term outcomes remain variable. In the last 2 decades, great advances have been made in understanding the genes and molecular biological mechanisms that underlie the disease. In addition, our understanding of normal enteric nervous system development and how motility develops in the developing fetus and infant has also increased. This review aims to draw these strands together to explain the developmental and biological basis of HSCR, and how this knowledge may be used in the future to aid children with HSCR.

Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
