Living with Drash syndrome

A genetic condition affecting the kidneys and genitals, with kidney disease starting in the first months of life and a high chance of Wilms tumor.

Understanding Drash syndrome

Drash syndrome, also called Denys-Drash syndrome, is a genetic condition that affects the kidneys and genitals.

Kidney disease begins in the first few months of life. Scar tissue forms in the kidneys' tiny filtering blood vessels, which often leads to kidney failure in childhood. GARD estimates a 90 percent chance of developing Wilms tumor, a rare kidney cancer. Males have testes that haven't descended and genitals that may not look clearly male or female. Females usually have normal genitals and only the kidney features.

Signs & symptoms

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

  • Kidney disease (nephropathy)
  • Nephrotic syndrome (protein loss in urine)
  • High blood pressure
  • Wilms tumor (kidney tumor)
  • Genitals that don't look clearly male or female
  • Undescended testes (males)

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 cancer specialists, genetic specialists, hormone specialists and kidney 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.

Everyday life

Living with a rare condition is easier with support.

  • Connect with National Kidney Foundation and other patient organizations
  • Keep notes on symptoms, changes and questions for appointments
  • Ask about patient registries that help research
  • Look into financial aid and travel resources for care visits

GenesWT1

GARD says changes in the WT1 gene cause this condition. It is autosomal dominant, meaning one changed copy of the gene can cause it.
