A newly identified exonic mutation of the WT1 gene in a patient with Denys-Drash syndrome.
Tsuda M., Sakiyama T., Owada M., Chiba Y.
An 11 month old boy with hypospadias and bilateral undescended testes developed renal failure. Denys-Drash syndrome was suspected and molecular analysis of the WT1 gene was performed, although no Wilms' tumor was identified. Direct sequencing analysis of genomic DNA from this patient revealed a G to A transition resulting in 366Arg to Leu substitution in exon 8 which has hitherto not been described. This newly identified mutation will help in the understanding of functional domains and in making a diagnosis of Denys-Drash syndrome.
