Cancer Genetics and Cytogenetics vol:108 issue:2 pages:137-40
Cytogenetic and molecular cytogenetic analysis is reported in a series of 40 tissue samples from 36 patients with Dupuytren's disease, presenting as palmar and/or finger nodules. No consistent structural chromosome changes could be found. Instead, recurrent clonal numerical abnormalities were demonstrated in 22 of 40 tissue nodules, involving trisomies of chromosome 7 or 8 and loss of the Y chromosome. In addition, we showed that trisomy 7 and trisomy 8 were also present in non-dividing cells.
