Frasier syndrome: ambiguous genitalia and end-stage chronic kidney disease in childhood. Case report
Abstract
We report the case of a patient with Frasier syndrome: nephropathy, gonadal dysgenesis and progressive and severe kidney damage during childhood. Frasier syndrome is a rare disorder that causes end-stage chronic kidney disease, usually in young adults —second or third decades of life. Nephropathy presents with proteinuria, beginning during childhood, occasionally with nephrotic syndrome; its characteristic histological lesion is a focal segmental glomerulosclerosis, resistant to treatment with corticosteroids and/or immunosuppressants. Frasier syndrome is caused by mutations in the Wilms’ tumor suppressor gene, or WT1 gene, located on the short arm of chromosome 11: Cr11p23.
