Denys–Drash syndrome Classification and external resources OMIM 194080 DiseasesDB 31499 eMedicine ped/564 MeSH C04.557.435.595.220 Denys-Drash syndrome is a syndrome characterized by the following conditions:
- gonadal dysgenesis
- nephropathy
- Wilms tumor
Denys-Drash Syndrome (DDS) is a very rare disorder.
Contents
Etiology
The cause of DDS is most commonly (96% of patients) an abnormality in the WT1 gene (Wilms tumor suppressor gene). These abnormalities include changes in certain exons (9 and 8) and mutations in some alleles of the WT1 gene. Genetically, the syndrome is due to mutations in the Wilms tumor suppressor gene, WT1, is on chromosome 11 (11p13). These mutations are usually found in exons 8 or 9 but at least one has been reported in exon 4.[1]
Presentation and clinical course
The presenting characteristics of DDS include loss of playfulness, decreased appetite, weight loss, growth delay, abnormal skeletal development, insomnia, abdominal pain, constipation, and anuria.
Clinically, Denys-Drash is characterized by the triad of pseudohermaphroditism, mesangial renal sclerosis, and Wilms tumor. The condition first manifests as early nephrotic syndrome and progresses to mesangial renal sclerosis and ultimately renal failure, usually within the first three years of life.
