Abstract
A human gene termed APC is disclosed. Methods and kits are provided for assessing mutations of the APC gene in human tissues and body samples. APC mutations are found in familial adenomatous polyposis patients as well as in sporadic colorectal cancer patients. APC is expressed in most normal tissues. These results suggest that APC is a tumor suppressor.

- 5. A nucleic acid probe complementary to all or part of human wild-type APC gene coding sequences or the complement of said sequence such that said probe selectively hybridizes under stringent conditions to said APC gene or identifies endogenous, random modifications in said APC gene.
-
7. A set of probes useful for detecting alteration of wild-type APC genes comprising a plurality of nucleic acid probes wherein said set is complementary to all nucleotides of the APC gene coding sequences as shown in SEQ ID NO:
- 1 or the complement of said sequences.
- 8. A pair of signal stranded DNA primers for determination of a nucleotide sequence of an APC gene by polymerase chain reaction, the sequence of said primers being derived from said APC gene, wherein the use of said primers in a polymerase chain reaction results in synthesis of DNA having all or part of the sequence shown in FIG. 7 (SEQ ID NO:
