Living with Meacham syndrome

A rare genetic condition from birth with diaphragm, genital, and heart differences.

Understanding Meacham syndrome

Meacham syndrome is a rare condition with multiple birth differences, including a diaphragm hernia and genital and heart defects.

Features include differences in the diaphragm, genital differences, and heart differences. It can include underdeveloped lungs. It starts in newborns and infants.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Hernia in the diaphragm
  • Underdeveloped lungs
  • Underdeveloped left side of the heart
  • Unclear external genitalia
  • Closed or absent vagina
  • Undescended testes

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 genetic specialists, hormone specialists, maternal-fetal medicine specialists and urinary and male reproductive system specialists.

  3. Consider genetic testing

    Changes in WT1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
