Summary

Aganglionosis, a condition affecting nerve cells in the gut, was found in 24% of patients with associated anomalies. Early detection and understanding of these congenital conditions are crucial for patient management and genetic counseling.

Area of Science:

  • Pediatric Gastroenterology
  • Clinical Genetics
  • Developmental Biology

Background:

  • Aganglionosis, a congenital disorder affecting the enteric nervous system, is characterized by the absence of ganglion cells in the distal bowel.
  • Associated congenital anomalies are frequently observed in patients with aganglionosis, impacting diagnosis and management.
  • Understanding the spectrum and genetic basis of these anomalies is crucial for clinical practice and genetic counseling.

Purpose of the Study:

  • To investigate the incidence and types of associated anomalies in a cohort of patients diagnosed with aganglionosis.
  • To highlight the clinical significance of recognizing these anomalies for patient care and genetic counseling.
  • To explore the potential developmental origins of aganglionosis and its associated anomalies.

Main Methods:

  • Retrospective case series analysis of 21 patients diagnosed with aganglionosis.
  • Detailed review of patient records to identify and document associated congenital anomalies.
  • Classification of anomalies based on established syndromic diagnoses and phenotypic descriptions.

Main Results:

  • Five out of 21 patients (24%) with aganglionosis presented with associated anomalies.
  • Identified anomalies included trisomy 21, Smith-Lemli-Opitz syndrome type II, persistent Müllerian duct syndrome, supernumerary digits, and segmental hypopigmentation.
  • The observed incidence suggests a potential under-reporting of anomalies in clinical practice.

Conclusions:

  • Aganglionosis can be associated with a diverse range of congenital anomalies, indicating potential links to broader developmental defects.
  • These findings underscore the importance of thorough clinical evaluation for associated anomalies in patients with aganglionosis.
  • Recognizing these associations aids in individualized patient management, genetic counseling, and understanding the embryonic etiology of aganglionosis.
