Mutations that alter normal splice patterns and genomic rearrangements are common causes of hereditary diseases including hereditary nonpolyposis colorectal cancer. However, abnormal transcripts can be difficult to detect and interpret because splicing patterns are often heterogeneous even in normal cells. Standard techniques including sequencing and Southern hybridization fail to detect some g...

Approximately 6% of colorectal cancers can be attributed to recognizable heritable germline mutations. Familial adenomatous polyposis is an autosomal dominant syndrome classically presenting with hundreds to thousands of adenomatous colorectal polyps that are caused by mutations in the APC gene. Adenomas typically develop in the midteens in these patients, and colorectal cancer is a virtual cer...

Hereditary nonpolyposis colorectal cancer is associated with inherited defects in DNA mismatch repair. Clinical variation even in cases with identical predisposing mutations suggests the existence of other factors contributing to the phenotype. We addressed the modifying role of the common A/G polymorphism in exon 4 and the alternatively spliced transcripts a and b of the CCND1 gene encoding cy...
