title: Chromosome 14q+ in a retinoblastoma.
abstract: A chromosome 14q+ was found in the tumor cells of a patient with sporadic, bilateral retinoblastoma. Eighty-six per cent of the metaphases contained the marker. Some metaphases showed a chromosome 6q--in addition. The question of the specificity of such markers in lymphoid malignancies is raised.
