ABSTRACT
The Wilms' tumor gene (WT1) encodes a protein that is believed to exert transcriptional and tumor-suppressor activities. Mutations in this gene have occasionally been associated with Wilms' tumor (<15% patients) and, more consistently, with three syndromes characterized by urogenital abnormalities (WAGR, Denys-Drash and Frasier syndromes). We report 17 years follow-up of a 29 year-old phenotypic female with 46,XY karyotype, gonadal dysgenesis and nephronophthisis in order to identify possible germline alterations of the WT1 gene. Frasier syndrome was suspected and confirmed by genetic analysis. Sequence analysis permitted the identification of an A40-->G mutation in position +5 in the donor splice site of intron 9. During surgery for streak gonads extirpation, a microscopic gonadoblastoma was found, a typical complication of Frasier syndrome.
