1. A method for assessing a genetic predisposition of an animal for a skin cancer, the method comprising:
- detecting, from a sample of nucleic acid isolated from the animal, a loss-of-function mutation in a patched gene in the germline of said animal,wherein the presence of said loss-of-function mutation indicates that said animal has a genetic predisposition for basal cell carcinoma.

Abstract
Methods for isolating patched genes, particularly mammalian patched genes, including mouse and human patched genes, as well as invertebrate patched genes and sequences, are provided. Loss-of function of the patched is associated with the occurrence of human cancers, particularly basal cell carcinomas of the skin. The cancers may be familial, having as a component of risk an inherited genetic predisposition, or may be sporadic. Therefore, methods for using the patched gene as a diagnostic for assessing a genetic predisposition to cancer, and to identify specific cancers having mutations in this gene, are disclosed.

- 6. A method for determining a patched phenotype of cells of a tumor comprising detecting, from a sample of nucleic acid isolated from the cells, the presence or absence of a loss-of-function mutation of a patched gene in the cells.

10. An assay for determining the patched phenotype of a cell, comprising
providing a nucleic acid sample isolated from mammalian cells, detecting the presence or absence of a patched gene sequence or allelic variant thereof, by hybridization of the nucleic acid sample with one or more nucleic acid probes which hybridize to a mammalian patched gene.
- 26. An assay for detecting mutations of a patched gene, comprising detecting, in a sample of isolated mammalian cells or nucleic acid isolated therefrom, the presence or absence of a deletion of one or more nucleotides from the patched gene, an addition of one or more nucleotides to the patched gene, a substitution of one or more nucleotides of the patched gene, a chromosomal rearrangement of all or a portion of the patched gene, an alteration in the level of an mRNA transcript of the patched gene, or alteration of the splicing pattern of an mRNA transcript of the patched gene.
- 32. An assay for phenotyping the patched status of a cell, comprising detecting, in a sample of isolated mammalian cells, the presence or absence of a genetic lesion of a patched gene characterized by at least one of (i) aberrant mutation of a patched gene resulting in loss of function, and (ii) mis-expression of the patched gene resulting in loss of function.

43. A method for assessing a genetic predisposition of an animal for developing basal cell nevus syndrome, the method comprising:
-
detecting, from a sample of nucleic acid isolated from the animal, a loss-of-function mutation in a patched gene in the germline of said animal, wherein the presence of said loss-of-function mutation indicates that said animal has a genetic predisposition for developing basal cell nevus syndrome. - View Dependent Claims (44)
