Catalase is known to map at chromosome 11p13. It is one of the closest known markers to the WAGR locus. Restriction fragment length polymorphisms (RFLP) of the catalase gene may be invaluable for studying rearrangements in somatic tumours, linkage in cases of familial Wilms tumour, and the relationship between sporadic and familial aniridia. We describe a catalase RFLP with two different enzymes and use these polymorphisms to exclude deletion of the catalase gene in patients with sporadic aniridia, including one who is known to have a deletion and another suspected of having a deletion.

Two unrelated patients with clinical features of 11p13 deletion syndrome, 3 years old and 3 months old, are reported. The clinical features of the patients included mental retardation, aniridia, nystagmus, blepharophimosis, and genitourinary abnormalities. Both patients were apparently free from Wilms' tumor and gonadoblastoma. Prometaphase banding analyses revealed a 46,XY,del(11)(p1300p1500) karyotype in one patient and 46,XX,dir ins(11;2)(p13;q12q23) in the other. Catalase activities in the erythrocytes in the two patients were respectively 65% and 56% of those of normal controls, close to the expected values in hemizygosity of the catalase gene. These findings confirmed a close linkage of the gene for catalase and those for the aniridia--Wilm's tumor or gonadoblastoma complex.
