Conclusions
The work described in this commentary
clearly shows both the feasibility and the impact of population-based
testing in individuals
of AJ descent. Individuals of AJ descent who are
identified through population-based screening have been demonstrated to
have
the same cancer risks as those identified based on
the strength of their personal or family history, and those with
mutations
have a high uptake of cancer screening and
risk-reducing options. Additionally, population-based testing has been
shown to
be feasible, and such testing importantly results
in a doubling of the numbers of carriers identified. Based on all of
these
factors, we believe that the time has come to offer
population-based testing to individuals of AJ descent. Mechanisms must
exist to provide appropriate pretest and posttest
genetic counseling. Further efforts are needed to validate alternatives
to traditional genetic counseling and to address
the potential insurance and other barriers to testing.
