  • Abstract
  • Look Inside

Using skin fibroblasts, chromosomal analysis was performed on 96 patients of retinoblastoma and 13 members of their family who visited the National Cancer Center Hospital in Tokyo. Chromosomal abnormalities were found in 6 cases of retinoblas-toma and one non-affected mother. The incidence of chromosomal abnormality was 13% in 40sporad-ic bilateral cases, 7% in 14 familial bilateral eases and 0% in 42 unilateral cases. Five cases showed interstitial deletion which involved at lease q 14 of Chromosome No. 13. One case was a de novo translocation of q22 ; q14 of Chromosome 13 to Chromosome 10.
