Abstract
DESCRIPTION: (Applicant's Description) Inherited predispositions to
specific cancers due to high penetrance alleles of genes such as APC and
BRCA1 account for only a small percentage of our populations cancer burden.
Genetic epidemiological evidence suggests, however, that a much higher
percentage of individuals may be at risk due to the inheritance of alleles,
or combinations of alleles, that individually show only a relatively low
cancer penetrance. This makes it difficult to analyze the associated
patterns of inheritance, localize the loci and identify the specific genes
involved. Large sample populations are now required to map and identify
these genes. We propose establishing a consortium consisting of the
Universities of Colorado, New Mexico and Utah whose primary purpose will be
to enroll a study population and create an infrastructure to support this
next generation of exploration of the genetics of cancer. A
population-based approach is needed to understand the population
significance of future findings. State cancer registries provide an
appropriate avenue of ascertainment. It is also important to develop a
study population enriched for predisposed individuals. Our approach,
therefore, is to ascertain individuals with one or more relatives who have
been diagnosed with the specific cancer. Specifically, we propose initially
to contact each individual diagnosed with breast, prostate, or colorectal
cancer in calendar 1998 and 1999 and determine: 1) whether they are willing
to participate and 2) have first-degree relatives affected with their same
cancer. If so, they will be recontacted and asked to provide more detailed
information regarding family history, as well as demographic and
epidemiologic information. Selected index cases will be requested to
complete questionnaires, which will include the names of their first-degree
relatives and their permission to contact these relatives. The first-degree
relatives will then be contacted and invited to enroll as members of the
Cancer Genetics Network. This approach will create a study population of
family members who have had cancer and who are at risk for cancer. We will
also offer enrollment to appropriate individuals who have already contacted
our high-risk clinics or are enrolled in ongoing clinical protocols of
familial cancer; for example, Colorado will extend their current research
interests by collecting lung cases. In addition, we will establish or
enhance clinical and laboratory core facilities, as well as the necessary
capabilities in genetic counseling, informatics and database management. As
study groups are enrolled, DNA samples may be collected and pilot projects
initiated; these include sib-pair studies and candidate-gene analysis funded
by the Huntsman Cancer Institute and the University of Colorado Cancer
Center.
