ABSTRACT

RESUMEN Se reporta un paciente con síndrome de Frasier: nefropatía, disgenesia gonadal y daño renal progresivo y severo durante la infancia. El síndrome de Frasier es una entidad poco frecuente, que ocasiona enfermedad renal crónica terminal, por lo general, en adultos jóvenes, segunda o tercera décadas de la vida. La nefropatía se manifiesta con proteinuria, de inicio en la infancia, ocasionalmente con síndrome nefrótico, siendo la lesión histológica característica una glomeruloesclerosis focal y segmentaria, resistente al tratamiento con corticoides y/o inmunosupresores. La causa genética del síndrome de Frasier corresponde a mutaciones del gen supresor del tumor de Wilms o gen WT1 localizado en el brazo corto del cromosoma 11: Cr11p23.


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.
