  • Title: Catalase levels in patients with aniridia and/or Wilms' tumor: utility and limitations.
    Author: Ferrell RE, Riccardi VM.
    Journal: Cytogenet Cell Genet; 1981; 31(2):120-3. PubMed ID: 6273073.
    Abstract:
    The gene for red blood cell (RBC) catalase has recently been mapped to 11p13, and a gene dosage effect has been demonstrated for individuals with triplication or deletion of that region. Deletion of the 11p13 band has also been associated with aniridia, with and without Wilm's tumor. We studied the RBC catalase levels in individuals without detectable chromosomal abnormalities but with aniridia, Wilm's tumor, and the combination of aniridia and Wilms' tumor, to determine whether catalase levels might provide evidence for a submicroscopic chromosomal deletion in the 11p13 region. All karyotypically normal patients were found to have normal catalase levels.
