Living with SERKAL syndrome

A rare genetic syndrome present before birth with female-to-male sex reversal and differences in the kidneys, adrenal glands, and lungs.

Understanding SERKAL syndrome

SERKAL syndrome is a rare genetic syndrome with sex reversal and differences in the kidneys, adrenal glands, and lungs.

The name stands for SEx Reversion, Kidneys, Adrenal and Lung dysgenesis. It involves female-to-male sex reversal and underdeveloped kidneys, adrenal glands, and lungs. It begins during pregnancy.

Signs & symptoms

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

  • Sex reversal
  • Absent kidneys
  • Underdeveloped lungs
  • Low amniotic fluid in pregnancy
  • Adrenal gland differences
  • Heart and diaphragm differences

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 and urinary and male reproductive system specialists.

  3. Consider genetic testing

    Changes in WNT4 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
