Abstract

Retinoblastoma is a childhood tumor that can arise because of mutant alleles acquired as somatic or germinal mutations. The mutant allele can be carried in the germ line. The mutations creating these alleles act by inactivating copies of a recessive oncogene located within band q14 of chromosome 13 and termed the RB1 locus. We have reported isolation of a cDNA fragment that recognizes chromosomal sequences possessing many of the attributes of the retinoblastoma gene associated with the RB1 locus. We now report that this segment is additionally the target of somatic mutations in mesenchymal tumors among patients having no apparent predisposition to retinoblastoma and no previous evidence of retinoblastoma. These tumors provide additional evidence that the cloned sequences are representative of a gene that is a frequent target of inactivation during tumorigenesis. Sequence analysis of this cDNA provides little insight into its normal functional role.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
