[WAGR syndrome, Wilms' tumor, aniridia, gonadoblastoma, mental retardation: a review apropos of 2 cases].

From 41 reviewed cases and 2 personal observations of the WAGR syndrome, the main symptoms and their relative frequency are described: aniridia, mental retardation, Wilms' tumor. Sexual anomalies and gonadoblastoma are less frequent. The chromosomic micro-deletion can be shown by using highly sophisticated cytogenetic techniques, or suspected by blood enzymatic dosage (mainly catalase). Kidney echographic follow-up is highly recommended.
