A gene dosage effect for catalase (CAT) was investigated in three individuals : one with 11p13 deletion, aniridia, ambiguous genitalla, and gonadoblastoma ; one trisomic for 11p with the exception of 11p13; and one trisomic for 11p13. Results were compatible with the assignment of CAT to 11p13 and its linkage with the aniridia-gonadoblastoma or Wilms' tumor complex (WAGR).
