title: [Cytogenetics of Paget's disease of bone].
abstract: The authors studied the karyotype in blood and marrow of 34 patients with Paget's disease and compared the results with those of a control group of the same age. Structural abnormalities are more frequent in the blood than in the marrow, but there is no significant difference in comparison with the abnormalities in the control group. Ionizing radiations and drugs do not seem to be responsible for the abnormalities encountered. The numerical abnormalities are characterized by an increase in the number of hypodiploidies, particularly involving the chromosome groups A, B and D, whereas chromosomal damage affecting the C and G groups is less than normal. These abnormalities were encountered in a limited number of patients. The authors discuss the significance of these chromosomal abnormalities in the more general context of the genetics of Paget's disease.
