Summary

CATCH 22 syndrome, a complex genetic disorder from a chromosome 22q11 deletion, presents with cardiac defects, facial anomalies, and hypocalcemia. This condition encompasses several related syndromes, including DiGeorge and velocardiofacial syndrome.

Area of Science:

  • Genetics
  • Developmental Biology
  • Medical Science

Background:

  • CATCH 22 syndrome is a complex genetic disorder.
  • It arises from a deletion on chromosome 22q11.
  • The syndrome encompasses multiple related conditions.

Observation:

  • Characterized by cardiac defects.
  • Includes abnormal facial features.
  • Associated with thymic hypoplasia, cleft palate, and hypocalcemia.

Findings:

  • The genetic basis is a deletion within chromosome 22q11.
  • CATCH 22 syndrome is an umbrella term for DiGeorge syndrome, conotruncal anomaly face syndrome, and velocardiofacial syndrome.
  • Presents a spectrum of congenital anomalies.
