Topic Overview

A brief educational segment defining CHARGE syndrome, a congenital disorder whose acronym stands for coloboma, heart defects, choanal atresia, retardation of growth and development, genital/urinary anomalies, and ear malformations. The discussants explain that while CHARGE is caused by CHD7 mutation on chromosome 8, clinical diagnosis is possible without genetic confirmation. Diagnostic criteria require either three major plus one minor feature, or two major plus two minor features; major criteria include coloboma, choanal atresia or cleft palate, characteristic ear abnormalities, and cranial nerve abnormalities.

Key Takeaways

  • CHARGE syndrome is caused by CHD7 mutation on chromosome 8, but some patients test negative and require clinical diagnosis. (0:11)
  • Clinical diagnosis requires 3 major + 1 minor feature, or 2 major + 2 minor features, even without genetic confirmation. (0:24)
  • Four major criteria: coloboma, choanal atresia/cleft palate, characteristic ear abnormalities, cranial nerve abnormalities. (0:28)
