Living with Lymphedema-atrial septal defects-facial changes syndrome

A rare inherited condition with swelling of the legs from birth, a heart wall opening, and a distinctive face.

Understanding Lymphedema-atrial septal defects-facial changes syndrome

Lymphedema-atrial septal defects-facial changes syndrome is a rare condition with leg swelling from birth, an atrial septal defect (hole between the upper heart chambers), and a characteristic facial appearance.

The face is round, with a prominent forehead, a flat nasal bridge with a broad tip, eye folds, a thin upper lip, and a cleft chin. It has been described in two brothers and a sister. It begins in newborns and infants.

Signs & symptoms

GARD doesn't list a separate symptom list. Its summary describes these features:

  • Swelling of the legs from lymph fluid (lymphedema)
  • Atrial septal defect (heart wall opening)
  • Round face with a prominent forehead
  • Flat nasal bridge and broad nasal tip
  • Cleft chin
  • Thin upper lip

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
