Abstract
A new mutation in WT1 is described in a sporadic unilateral Wilms’ tumour consisting of a 17 bp duplication in exon 7 generating a stop codon. The second allele is either partially deleted or presents the same alteration. LOH analysis at 11p15.5 and at the 16q13-16q24.3 regions indicated retention of heterozygosity in the tumour DNA for the markers analysed. The results are consistent with Knudson’s hypothesis and confirm that loss of function of WT1 contributes to the development of at least some Wilms’ tumours.
