Abstract
The Wilms tumor gene (WT1) encodes a transcription factor that plays a key role in the laying and differentiation of the kidneys and gonads. Mutations of the WT1 gene were detected in patients with the WAGR complex (Wilms tumor, aniridia, urogenital pathology, mental retardation), Denis-Drach syndrome (early renal failure, diffuse mesangial sclerosis, varying degrees of gonadal dysgenesis, high risk of Wilms tumor) and Fraser syndrome. The latter is characterized by a fully female phenotype with karyotype 46XY, focal segmental glomerulosclerosis with the development of renal failure in the 2nd decade of life, gonads in the form of cords and a high risk of gonadoblastoma. The presence of a heterozygous point mutation, which alters the donor site of splicing of the intron 9 of the WT1 gene, is also typical of Fraser syndrome. We present a case of characteristic clinical manifestations of Fraser syndrome in a patient in whom the diagnosis was confirmed by the detection of a mutation in the WT1 gene.
