Living with Lung fibrosis-immunodeficiency-46,XX gonadal dysgenesis syndrome

A rare inherited condition that affects the immune system, the ovaries or gonads, and the lungs, beginning in infancy.

Understanding Lung fibrosis-immunodeficiency-46,XX gonadal dysgenesis syndrome

Lung fibrosis-immunodeficiency-46,XX gonadal dysgenesis syndrome is a rare inherited condition with immune deficiency, gonadal dysgenesis, and lung fibrosis (scarring).

People typically have a 46,XX chromosome pattern. Gonadal dysgenesis means the gonads (reproductive glands) did not develop as usual. It begins in infancy.

Signs & symptoms

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

  • Weak immune system (immune deficiency)
  • Underdeveloped gonads (gonadal dysgenesis)
  • Scarring of the lungs (lung fibrosis)

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

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include allergy and immune system specialists, genetic specialists, hormone specialists and lung and breathing specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Immune Deficiency Foundation may keep lists of experts for this condition.
