Four chromosomal regions were tested for loss of constitutional heterozygosity in primary tumours from 85 Icelandic breast cancer patients. Loss of heterozygosity and other types of gene rearrangements were observed in 37% of informative cases at the retinoblastoma locus, RB1, on chromosome 13q. Allele losses on chromosome 17 were tested with two polymorphic probes on 17p and two on 17q. Loss of heterozygosity or other types of genetic rearrangement were detected in 43.5% of cases on 17p near the p53 gene and 40.5% on 17q. In our study abnormalities at the RB1 locus and on chromosome 17 frequently occurred together, indicating that the coincident inactivation of more than one tumour suppressor gene may, in some cases, play a part in tumour formation. No significant correlation was found between these losses and clinico-histological parameters. Family history of breast cancer was found to be more common among patients with RB1 deletions and this trend was strengthened in cases where there were deletions at both the RB1 locus and on chromosome 17.
