The past several
years have fueled a revolution in human genetics and this revolution
is having a very significant impact on virtually all specialties
of medicine. There are several scientific advances that are responsible
for this revolution. One of them is the recognition that the genetic
composition of individual humans has a significant role to play
in that individual's health and predisposition to common diseases
such as heart disease and cancer. The second scientific advance
that is having a significant impact is the availability of the human
genome sequence and the many high throughput technologies that have
been developed in the human genome project. This new post-genomic
era provides excellent opportunities to identify genes, genetic
changes that are responsible for human disease, and in understanding
how such changes cause disease. In the clinical arena, it is becoming
possible to utilize the emerging genetic and genomic knowledge to
diagnose and treat patients. It is anticipated that such knowledge
would revolutionize medical practice to result in personalized medicine.
The knowledge of he genetic basis of human disease is ushering a
new era in drug development that is focused on targeted drug development.
Genetic profiling of individuals in clinical trials would help in
correlating individuals with their response to specific drugs.
To realize the promise of genetics and genomics in research and
in medical practice, we have established the Harvard Medical School-Partners
Healthcare Center for Genetics and Genomics. Its mission is:
MISSION: Promote Genetics and Genomics
in Research and Clinical Medicine
Harvard Medical School (HMS) and Partners
HealthCare System (PHS) established the Center for Genetics and
Genomics in 2001. Dr. Raju Kucherlapati was recruited to be the
first Scientific Director of this Center. The Center is accomplishing
its mission through a number of strategic approaches that are described
below.
The fields of Human Genetics and Genomics
have matured significantly during the past several years. The science
of Genomics enabled us to obtain the maps and DNA sequence of many
organisms, including the human, and it is now well established that
many aspects of human health and disease have a genetic basis. The
tools that have been developed to accomplish the mapping and sequencing
goals are promising to revolutionize medical research and clinical
practice. Harvard Medical School and the participating institutions
in Partners HealthCare possess a number of outstanding geneticists
and genomicists. The Center will bring together this great talent
to change the rate of discovery of genes involved in human disease,
as well as to develop programs that will assist in the understanding
of the roles of the large number of human genes and how changes
in these genes result in predisposition to common diseases. Most
importantly, the Center will strive to utilize this knowledge to
better manage and treat the large patient population served by the
Partners institutions.
The mission of the Center is being
accomplished through four approaches:
1. Establishment of an academic
unit
This academic unit is located in the
New Research Building on the Avenue Louis Pasteur in Boston. A second
academic unit will be a part of the MGH Genetics thematic center
and will be located in a new building on the main campus of MGH
that is scheduled to open in the summer of 2005. It is anticipated
that the space will house 12-14 new faculty members, a third of
who will be senior faculty. The research interests of the faculty
will be the general areas of mammalian genetics and Informatics,
with particular emphasis on individuals whose research interests
are focused on the development and application of genetic and genomic
tools for discovery of genes involved in common disorders. Other
faculty will include individuals whose research interests complement
several strong research programs at Harvard Medical School and Partners.
These areas include cardiovascular disease, cancer, pulmonary disorders
and neurologic, neurodegenerative and psychiatric illness. The Center
has already recruited two outstanding scientists and additional
recruitments are underway.
The Center will become a focus for
intellectual activity in human genetics and genomics by hosting
clinical and basic scientists who are committed to the mission of
the Center. The Center is sponsoring seminars, symposia and courses
to sharpen the focus on human genetics studies and its implications
to clinical medicine.
The Center is also working with the
Chairs and Division Chiefs to promote human genetic research and
genetic/genomic medicine at HMS, its affiliated hospitals and other
institutions in the greater Boston area.
2. Infrastructure for the Harvard-Partners
Community
The Center has built an infrastructure
that will ensure leadership in the areas of genetics and genomics
research, as well as the clinical application of new discoveries.
Partners Genome Center: We have
established a Harvard-Partners Genome Center in the new Partners
building at 65 Landsdowne Street in Cambridge. The Genome Center
is available for large-scale projects of sequencing and resequencing
of genes and genomes.
Partners Genetics consulation service:
In collaboration with the CCI at BWH the Center offers consulation
service for investigators about genetics study design and phenotyping.
Partners Genotyping Center:
This facility provides high throughput methods for microsatellite
and single nucleotide polymorphism (SNP) based genotyping of human
and mouse populations. The genotyping center utilizes many different
platforms and the current SNP genotyping has a capacity of more
than 100,000 genotypes per day. We anticipate that this capacity
will increase significantly in the near future. This Center will
also develop, evaluate and implement the most recent technologies
involving large-scale genotyping. It is anticipated that the facility
will act as an important resource for investigators who are interested
in using large-scale genomic methods for disease gene discovery.
Partners Genechip and Microarray
Facility: This microarray facility provides expression-profiling
technologies for all members of the HMS and PHS community. The Center
will support, extend and help modernize several existing gene chip
facilities. The Center will provide commercial as well as high quality
"home-made" gene arrays at affordable prices to all members
of the community. The Center is currently makes available human,
mouse and Drosophila arrays. The Center's facilities, in conjunction
with existing facilities, also provides hybridization, washing and
data acquisition services on a fee-for-service basis. It will also
provide Informatics tools and expertise for analysis and interpretation
of the profiling data.
Partners Proteomics facility:
This facility has mass spectrometry units. This
facility provides consultation to investigators about proteomics studies. It
also helps in the design and execution of experiments as well as data analysis.
One of the goals of this facility is to develop technologies for identification
of disease biomarkers.
Harvard, HMS and PHS Center for
Physiological Genomics: New high throughput methods are becoming
available for rapidly annotating the genomes of many organisms (functional
genomics). High throughput methods for detailed and accurate phenotyping
of mouse mutants and human patients are becoming available (physiological
genomics). The Center, in collaboration with the FAS at Harvard
College, will develop and implement a plan to bring functional genomics
and physiological genomics to our scientific and clinical community.
3. Partners Laboratory of Molecular
Medicine
An important goal of the Harvard-Partners
Center for Genetics and Genomics is to translate the knowledge gained
from genetics and genomics to more accurately diagnose and treat
the large patient populations served by the Partners Hospitals.
Already several hundred genetic and genomic tests are available,
and it is expected that several thousand additional tests will become
available in the next few years. These tests are expected to help
in diagnosis and prognosis and also in determining the appropriate
drugs for individual patients. The Partners Laboratory of Molecular
Medicine is a CLIA and state approved laboratory that provides genetic
and genomic testing for patients around the world. It is also a
leader in the development of new approaches to genetic testing and
its integration into health care.
4. Medical Genetics and Education
Clinical services in medical genetics
have traditionally been focused on the diagnosis, management, and
counseling of rare single gene or chromosomal disorders. However
new knowledge of genetics and genomics is catalyzing an expansion
that will encompass all areas of medicine. The Center has established
clinical services at Massachusetts General Hospital and Brigham
and Women's Hospital, and will provide services for all of the Partners
hospitals. In addition, it is developing collaborative programs
with other departments and divisions to incorporate genetics into
the care of patients throughout the existing system. It is also
devising tools that will enable primary care physicians to provide
their patients with appropriate advice, testing, and referral to
address genetic problems in disease prevention and management.
The rapid pace of advancement of knowledge
in genetics and genomics poses a major educational challenge for
all health providers, investigators, and the public. The Center
will play a leadership role in providing education on the importance
of genetics in human health and disease and the ethical, legal and
social implications of this knowledge. Teaching programs will include
education for medical students, nurses, practicing physicians, and
other health professionals. In addition. the Center will expand
its educational mission by developing novel teaching tools for high
school and college students as well as the general public.
