title: High resolution chromosome results in retinoblastoma families.
abstract: In three families in the North of England, where retinoblastoma is transmitted, 41 members were studied by high resolution chromosome banding at the 500+ and 900+ levels. None of the 10 affected individuals or their normal relatives showed any deletion in the 13q14 region.
