Abstract

Aims and background The MutY human homologue gene (MUTYH) is responsible for about a quarter of attenuated familial adenomatous polyposis. Occasionally, it has been associated with hyperplastic polyps and serrated adenoma. We report a family where the same MUTYH mutation determined four different phenotypes, including a case of hyperplastic polyposis syndrome. Patients and methods A family with a history of right-sided colon cancer and multiple colonic polyposis was investigated. Genetic tests were correlated with clinical findings to define phenotypic manifestations of MUTYH mutations. The pertinent English-language literature was reviewed to evaluate the risk of malignancy of MUTYH and the role of prophylactic surgery. Results Three male siblings carried a biallelic MUTYH mutation (G382D-exon13), while the fourth was heterozygote. One developed an isolated cecal cancer at the age of 48. Another, aged 38, was diagnosed with numerous minute colonic and rectal polyps and underwent a proctocolectomy, with final pathology showing a picture of hyperplastic and lymphoid polyposis. The third biallelic brother, 46 years old, developed four hyperplastic lesions, while the heterozygote brother had a large flat serrated adenoma of the right colon removed at the age of 50. Conclusion Many aspects of MUTYH mutation still need to be clarified and one of them regards the different phenotypic expressions. Although the majority of reported cases manifested attenuated adenomatous polyposis, hyperplastic polyps and serrated adenomas appear to be more common than expected. Presenting hyperplastic polyposis syndrome is very unusual and may represent a clinical dilemma for correct management. Current evidence suggests to handle MUTYH-associated polyposis as typical FAP.

Abstract

An expert consensus panel convened by the Italian Association for Inherited and Familial Gastrointestinal Tumors (Associazione Italiana per lo Studio della Familiarita ed Ereditarieta dei Tumori Gastrointestinali, AIFEG) reviewed the literature and agreed on a number of position statements regarding the definition and management of polyposis coli without an identified pathogenic mutation on the APC or MUTYH genes, defined in the document as NAMP (non-APC/MUTYH polyposis).

Abstract

© The Author 2015. Published by Oxford University Press. All rights reserved. Numerous genetic factors that influence breast cancer risk are known. However, approximately two-thirds of the overall familial risk remain unexplained. To determine whether some of the missing heritability is due to rare variants conferring high to moderate risk, we tested for an association between the c.5791C>T nonsense mutation (p. Arg1931*; rs144567652) in exon 22 of FANCM gene and breast cancer. An analysis of genotyping data from 8635 familial breast cancer cases and 6625 controls from different countries yielded an association between the c.5791C>T mutation and breast cancer risk [odds ratio (OR) = 3.93 (95% confidence interval (CI) = 1.28-12.11; P = 0.017)]. Moreover, we performed two meta-analyses of studies from countries with carriers in both cases and controls and of all available data. These analyses showed breast cancer associations with OR = 3.67 (95% CI = 1.04-12.87; P = 0.043) and OR = 3.33 (95% CI = 1.09-13.62; P = 0.032), respectively. Based on information theory-based prediction, we established that the mutation caused an out-of-frame deletion of exon 22, due to the creation of a binding site for the pre-mRNA processing protein hnRNP A1. Furthermore, genetic complementation analyses showed that the mutation influenced the DNA repair activity of the FANCM protein. In summary, we provide evidence for the first time showing that the common p. Arg1931* loss-of-function variant in FANCM is a risk factor for familial breast cancer.
