The results further support the concept that the human RB1 gene has pleiotropic effects on specific types of cancer.
Abstract
Structural changes of the human retinoblastoma gene have been demonstrated previously in retinoblastoma and some clinically related tumors including osteosarcoma. Structural aberrations of the retinoblastoma locus (RB1) were observed in 25% of breast tumor cell lines studied and 7% of the primary tumors. These changes include homozygous internal deletions and total deletion of RB1; a duplication of an exon was observed in one of the cell lines. In all cases, structural changes either resulted in the absence or truncation of the RB1 transcript. No obvious defect in RB1 was detected by DNA blot analysis in primary tumors or cell lines from Wilms' tumor, cervical carcinoma, or hepatoma. These results further support the concept that the human RB1 gene has pleiotropic effects on specific types of cancer.

Although heterozygosity in constitutional DNAs was often preserved in tumour DNAs, one case developed homozygosity for chromosome 11p markers in tumours, implying the involvement of chromosomal events in revealing a recessive WT locus, which suggests the action of such general mechanisms in a tumour other than retinoblastoma.
