title: Factors influencing uptake of genetic testing for colorectal cancer risk in an Australian Jewish population.
abstract: There is a significant excess of colorectal cancer in the Australian Ashkenazi Jewish community. This excess can partially be attributed to inherited factors that are over represented in this population, such as the APC variant I1307K, which is associated with a modest increase in colorectal cancer risk. There is currently only sporadic clinical genetic testing offered for this variant, as neither the exact increase in cancer risk and therefore the appropriate screening strategies for I1307K carriers, nor the acceptability of such testing in Jewish communities have been determined. This study reports a high acceptability of such genetic testing within a community sample of 300 Australian Jewish individuals--94% of participants would have a test for predisposition to colorectal cancer and a majority would make this decision based on the desire for information for their families and to decrease their own cancer risk. Some concerns were noted about genetic testing for cancer predisposition, including insurance discrimination, test accuracy and confidentiality.
