The anonymous DNA fragment B79a, which had previously been located to chromosome 7cen-7q22, has been more accurately assigned to 7q22 by dosage analysis in a patient hemizygous for a deletion of that region. By examination of a panel of genomic DNAs from unrelated individuals, digested with a number

โฆ Synopsis
The gene locus for hereditary retinoblastoma is on human chromosome 13, band q14. With this gene localization in mind, we cloned DNA fragments from this chromosome. Three of the fragments identify restriction fragment length polymorphisms. These three fragments are from the region 13q12-13q22, the chromosome region which contains the retinoblastoma locus. We expect that these restriction fragment length polymorphisms will be linked to the retinoblastoma locus, and that they will serve in certain retinoblastoma families as predictors of retinoblastoma gene carriers. They will also be useful in studies of other gene loci thought to be on chromosome 13.
