GENETIC INFORMATION NONDISCRIMINATION ACT OF 2005
Mr. ENZI. Mr. President, I rise to speak on the promise of genomics.
``Dazzling thrilling astonishing breathtaking''. Even for a group
given to hyperbolic speech, the language my
[[Page S1596]]
colleagues used in this Chamber 2 years ago to describe advances in
human genetics is both extraordinarily intense and factually accurate.
Little has changed since 2003. Indeed, little has changed in the 9
years we have been considering this legislation. What remains the same
is that the tremendous promise of this fundamental scientific advance
remains incompletely realized. I am truly concerned that, at the very
time in healthcare that we need innovation the most, we tacitly accept
limitations on the application of this ``tremendously powerful tool.''
It is vital to understand that we have hurtled forward, over a
remarkably short period of time, into an entirely new era of medical
practice, one the majority leader believes will be characterized by
``advances . . . more dramatic than any . . . I had the opportunity to
. . . participate in over twenty years in . . . medicine''. Barely 50
years ago, Drs. James Watson and Francis Crick completed the work begun
by the 19th century Austrian monk, Gregor Mendel, when they discovered
the double-helix structure of DNA, the substance of which genes are
composed. Four nucleotides, a simple combination of phosphate, nucleic
acids and sugar, are arranged in an infinite variety of pairs within
genes that, in turn, are distributed amongst the 46 chromosomes, which
constitute the normal human genome. Operating according to the
instructions contained in the DNA, cells in the body produce proteins
that control the expression of our individual heredity, e.g. color of
hair and eyes, and determine, in part, whether we will be sick or well.
Hardly 2 years ago, Dr. Francis Collins and colleagues at the NIH
National Human Genome Research Institute completed mapping of the human
genome, determining the exact location of the 3.1 billion base pairs
that constitute our ``blueprint of life''. It is encouraging to note
that, in an era where government programs are beginning to receive the
scrutiny the public deserves regarding results, this program completed
its Herculean task 2 years ahead of schedule. As representatives of the
people, we now have the opportunity and the responsibility to help
scientists and clinicians bring this basic research forward to the
hospital, the clinic, even to our very workplaces and homes. There are
many, both sick and well, who are counting on us to help put that
blueprint to use.
How does the science of genetics, simple and straightforward as it
may be to the experts, translate into something with meaning to those
outside the scientific community: the Congress; and the citizens whom
we represent? In particular, why should the rancher in Cody or small
businessman in Gillette care? I can think of three ways.
First, our Declaration of Independence states that we are ``endowed
by our Creator with . . . unalienable rights (including) life, liberty
and the pursuit of happiness''. Clearly, the state of our health can
determine how successfully we exercise at least two of those rights.
For example, patient care can be much more individualized if it is
based on an understanding of the human genome. Current medical practice
applies the results from studies obtained in groups of patients to the
treatment of the individual; within each group, however, there are
patients who respond better or worse to the therapy offered, compared
to the response of the group as a whole. The former may be undertreated
by standard therapy--they could recover faster or more completely,
while the latter may be overtreated--developing complications of
therapy that may prove worse than the disease itself. Providers need a
way to predict what an individual's response to treatment is likely to
be so that a particular course of therapy can be modified intelligently
and expeditiously. That flexibility in treatment, guided by an
understanding of the patient's unique, genetically determined response,
should result in better outcomes. Even today, oncologists are treating
cancer patients with protocols that take into account genetically
determined differences in how individuals absorb, metabolize and
excrete drugs. Drug therapy for other diseases should show similar,
clinically relevant variability. Similarly, cardiologists caring for
patients with hereditary long QT-interval syndrome, a disturbance in
heart rhythm that can lead to sudden death in healthy young people
during exercise, are beginning to use genetic testing to help select
patients for treatment or observation and to choose amongst the
therapeutic options available--lifestyle changes, drug therapy and
surgery--the ones most likely to be of benefit.
Second, we recognize, based on long experience, that prevention is
better than cure, both for the individual and for society as a whole.
Early identification of a genetic predisposition to develop a specific
disease can be crucial to an effective intervention, one that, quite
often, will be less costly, too. For example, cystic fibrosis--an
inherited disease producing life-threatening digestive and respiratory
symptoms--is the most common, recessively inherited condition
afflicting white American children. Scientists have identified over 700
genetic variations of cystic fibrosis, some of which help to define the
clinical manifestations of the disease. Treatment programs for cystic
fibrosis that emphasize preventive therapies are associated with the
best outcomes. Early identification of those at risk and more precise
characterization of what those risks will be facilitates a more
productive program of monitoring, more aggressive preventive care and
focused treatment. Likewise, sickle cell anemia, an inherited
abnormality in the production of hemoglobin, the molecule in the blood
that carries oxygen to the cells, is prevalent in African Americans.
Sickle cell disease, the most severe variant of this condition, carries
a significantly increased risk of disability and early death through a
variety of infectious and thrombotic complications. Changes in
lifestyle and compliance with regimens of preventive care, e.g.
prophylactic antibiotic therapy, are easier for affected individuals to
tolerate if they believe that the risks and benefits really apply to
them.
Some might argue that diseases like these, though unquestionably
worthy of public attention, represent a lesser national priority when
compared to the other health care needs. In addition, other pressing
domestic and international concerns--deficit reduction and national
security--figure prominently, as they should, in the national debate.
Wyoming has relatively few citizens at risk for some of the diseases I
highlighted today, so most citizens of my state might, understandably,
focus their thoughts elsewhere.
I think there are two reasons why they don't. The people of Wyoming
take appropriate responsibility for one another's well-being. They lend
a hand whenever help is necessary, not in the expectation that to do so
will be of direct benefit to them, but because it is, simply, the right
thing to do. There is a direct benefit, however, to be realized. Full
implementation of the results of the human genome project will have a
revolutionary impact on diseases that are of concern to all of us, in
Wyoming and across the United States, regardless of our age, gender, or
ethnicity. Already, experts recognize the practical and the potential
applications of genetic research to the diagnosis and treatment of
cancer--e.g., breast, colorectal and ovarian--heart disease,
degenerative neurological disease--e.g., Alzheimer's and Parkinson's--
diabetes, and asthma. No longer is it science fiction to anticipate
that primary healthcare providers will, by combining environmental risk
assessment and education with genetic evaluation, be able to develop,
implement and monitor a comprehensive, life-long health plan that
maximizes wellness.
Third, and, perhaps, most important of all, Americans must recognize
that they have a civic responsibility not only to care for their own
health, but to participate in the research yet to come that moves the
science of healthcare forward for everyone. Those of us, including
myself, who have contributed to this discussion over the last 9 years
have all noted the remarkable ``explosion of knowledge'' and the
``great strides'' in healthcare that have resulted from research
already performed. More importantly, though, we recognize that, while
the science of human genomics has ushered in a new era of vast
potential, that promise has not yet been fully realized. There is much
that remains to be done to ``unleash the power'' of this science to
change permanently the practice of healthcare for the better. Clinical
trials are still necessary, to validate
[[Page S1597]]
reasonable hypotheses and to determine where innovations should fit
into practice. Once integrated, the actual effect of these innovations
must be accurately and precisely assessed, recognizing that experience
is the great teacher. We must work to foster a culture of enlightened
self-interest in the American people, underscoring their altruistic
motivation to do what's right. Finally, we have a responsibility to
encourage our fellow citizens to participate fully in their own
healthcare by working with their providers to incorporate advances in
science into their personal health plans as quickly as possible.
Inherent in discharging this responsibility is the need to remove
barriers to action. Thomas Jefferson said, ``Laws and institutions must
go hand in hand with the progress of the human mind.'' No better
example of this truism exists than the challenge we face in fulfilling,
completely, the promise of the genomic revolution. Our objective is
clear: to encourage people to seek genetic services, and to participate
in essential genetic research, by reducing fears about misuse or
unwarranted disclosure of genetic information.
I applaud my colleagues in voting for the Genetic Information
Nondiscrimination Act of 2005.
The PRESIDING OFFICER (Mr. Isakson). The Senator from Oregon.
