Genetic Characterization of Chinese Hereditary Non-polyposis Colorectal Cancer by DHPLC and Multiplex PCR

Genetic characterization of Chinese hereditary non-polyposis colorectal cancer by DHPLC and multiplex PCR.

BACKGROUND Hereditary non-polyposis colorectal cancer (HNPCC) is an autosomal dominant disease due to germline mutations of human mismatch repair genes, mainly hMLH1 and hMSH2. The aim of the present study was to identify the point mutations and large genomic deletions of hMLH1 and hMSH2 genes in 14 Chinese HNPCC families. METHODS Fourteen families fulfilling the Chinese HNPCC criteria were i...

Evolution of hereditary non-polyposis colorectal cancer.

The prevalence of colorectal adenoma in 23 affected patients with hereditary non-polyposis colorectal cancer (HNPCC) was compared with that in an age matched forensic autopsy population. The mean ages at diagnosis of colorectal cancer in men (13) and women (10) were 39 and 37 years respectively. In HNPCC patients who presented below the age of 50 years, at least one adenoma was found in 3 of 10...

[Hereditary non-polyposis colorectal cancer (HNPCC)].

Hereditary non-polyposis colorectal cancer (HNPCC) is a type of hereditary colorectal cancer with autosomal dominant traits. Its causal genes are mismatch repair genes such as the hMSH2 and hMLH1 genes. Owing to its frequency, juvenile onset, and the outbreaks of multiple colorectal cancers and cancers occurring over multiple organs, it is recognized as a very important disease for the purpose ...

Genetic Basis of Hereditary Colorectal Cancers: Hereditary Nonpolyposis Colorectal Cancer and Familial Adenomatous Polyposis

Fordyce granules and hereditary non-polyposis colorectal cancer syndrome.

BACKGROUND Germline mutations in mismatch repair (MMR) genes are found in only about half of clinically diagnosed families with hereditary non-polyposis colorectal cancer syndrome (HNPCC) (or Lynch syndrome). Early identification of gene carriers is essential to reduce cancer incidence and overall mortality. AIMS Recent evidence indicates an increase in size and number of sebaceous glands fol...
