Drash syndrome — Clinical Guidelines

Overview

Drash syndrome is a rare genetic disorder characterized by male pseudohermaphroditism, progressive renal failure, and Wilms tumor, often associated with mutations in the WTX gene. 1 2 3 4 5

Diagnosis

Key Diagnostic Criteria:

- XY gonadal dysgenesis or ambiguous genitalia - Presence of proteinuria and/or nephrotic syndrome - Progressive renal insufficiency or glomerular disease (diffuse mesangial sclerosis) - Wilms tumor or predisposition to gonadal neoplasms

Recommended Tests:

- Genetic testing for WTX gene mutations - Renal function tests (creatinine, GFR) - Urinalysis for proteinuria and hematuria - Ultrasound for abdominal masses (Wilms tumor) - Renal biopsy to confirm glomerular changes 1 2 3 4 5

Management

First-Line Treatments:

- Early nephrectomy for Wilms tumor to prevent further renal damage 6 - Management of nephrotic syndrome with supportive care (diet, diuretics) 1 4

Adjunctive Treatments:

- Renal replacement therapy (dialysis, transplantation) for end-stage renal failure 6 - Prophylactic gonadectomy to prevent gonadal tumors 2 3

Drug Classes/Doses:

- No specific drug doses mentioned for primary treatment; supportive care with steroids often ineffective for nephropathy 1 4

Special Populations

Pediatrics:

- Early recognition crucial for managing Wilms tumor and renal complications 1 2 4 5 - Prophylactic nephrectomy and gonadectomy recommended 2 3

Comorbidities:

- Presence of hypertension managed with standard antihypertensive therapy 1 4

Key Recommendations

Suspect Drash syndrome in children with XY gonadal dysgenesis and seek urine protein levels; consult genetic and nephrology specialists if proteinuria is present. (Evidence: Moderate) 1

Consider prophylactic nephrectomy for Wilms tumor and gonadectomy to prevent gonadal neoplasms in patients diagnosed with Drash syndrome. (Evidence: Moderate) 2 3

Early recognition and management of nephrotic syndrome are essential, though steroid therapy is typically ineffective; focus on supportive care and monitor for progression to end-stage renal disease requiring dialysis or transplantation. (Evidence: Moderate) 1 4
