Overview
Causes
Wilms tumor is the most common form of childhood kidney cancer. The exact cause of this tumor in most children is unknown.
Molecular biology
Mutations of the WT1 gene on chromosome 11 are observed in approximately 20% of Wilms' tumors.[1][2] At least half of the Wilms' tumors with mutations in WT1 also carry mutations in CTNNB1, the gene encoding the proto-oncogene beta-catenin.[3]
A gene on the X chromosome, WTX, is inactivated in up to 30% of Wilms' tumor cases, according to research published in 2007.[4]
