Oral Pigmentation and Intestinal Polyposis

IN 1921 Peutz described a family with intestinal polyposis and spots of melanin pigmentation in and around the mouth. Prior to this, in 1896, Sir Jonathan Hutchinson described two girls with pigmented patches in the oral mucosa and around the mouth. Later, Parkes Weber (1919) reported that one of these twins died of what appeared to be an intussusception. Since 1921 over one hundred cases have ...

Genetic and Non-Genetic Factors in Pigmentation of Neurospora Crassa.

HE biochemical genetics of carotenoid pigments has been studied in the T tomato ( LEROSEN et al. 1941 ; MACKINNEY and JENKINS 1949 ; PORTER and LINCOLN 1950), corn (MANGELSDORF and FRAPS 1931) and red yeast (BONNER et al. 1946). HAXO (1949) worked out the carotenoid components of the wild type Neurospora. The present paper deals with genetic and biochemical studies of a modifier system for pigm...

Hereditary gastrointestinal polyposis: Diagnosis, genetic test and risk assessment

Colorectal cancer (CRC) is the second cause of cancer deaths, with over 1 million new cases estimated every year. Familial adenomatous polyposis, MUTYH-associated polyposis and hamartomatous polyposis are inherited syndromes that account for 2% 5% of all colon cancer. The mutated genes responsible for the vast majority of these disorders, are now known (MLH1, MSH2, MSH6, PMS2, APC, MYH, LKB1, S...

Genetic linkage analysis in hereditary non-polyposis colon cancer syndrome.

Hereditary Non-polyposis Colon Cancer Syndrome (HNPCC) is the most common cause of familial colorectal cancer. Molecular genetic studies of HNPCC have shown evidence of locus heterogeneity, and mutations in four genes (hMSH2, hMLH1, hPMS1, and hPMS2) which encode components of the mismatch enzyme repair system may cause HNPCC. To determine the extent and nature of locus heterogeneity in HNPCC, ...

Clinical and genetic problems in familial in-intestinal polyposis.

The history of a family suffering from familial intestinal polyposis is presented, showing how a delayed onset of symptoms together with a lack of knowledge of affected relatives may obscure the familial nature of the disease. The necessity of examining all accessible relatives, irrespective of their advancing years, is stressed. Further, it is shown that in the absence of any familial incidenc...
