Whole-exome sequencing unveiled a novel variant, c.1447 + 6(IVS9)T > C, in the WT1 gene, and karyotypic analysis revealed 46, XY, aligning with the phenotypic presentation of Frasier syndrome (FS, OMIM#136680) associated with WT1 gene mutation. This evidence concerns the gene WT1 and Feingold syndrome.
