Our purpose here is to describe our various research projects at the University
of Pittsburgh and elsewhere.
We have just recently begun updating this site, and hopefully improving it.
We hope to hear from you about it,
either good or bad.
We also very much hope that you will find the material presented here both
interesting and informative.
We wish you all the Best

The Bipolar Disorder Genetics Study
A quick overview of our study...
Our group at the University of Pittsburgh is seeking persons suffering from
bipolar disorder or
schizophrenia who are willing to take part in a research study. Our NIH
funded studies focus on
discovering genetic and environmental factors predisposing individuals towards
these and related illnesses,
with the ultimate goal of developing better treatments or preventative measures.
All we need from affected participants is several tablespoons of blood, and two
to three hours for a clinical interview.
In addition we need either an ill sibling willing to donate a blood sample and
give a clinical interview, and/or a parent(s)
willing to donate a blood sample. This is an international effort, and though
the U.S. group is based in Pittsburgh, Pa, we
have recruiters and interviewers based in the field that can in many cases meet
with families far away from this area.
Participants will receive $20 in appreciation for their time and trouble, and
all expenses which might be incurred will be covered by us.

We apreciate your interest in our research into the causes of schizophrenia,
bipolar disorder and related illnesses.
Mental health care consumers might find this site of interest, as might their
families
This is the first issue of a newsletter describing our research
into the causes of serious psychiatric illnesses like schizophrenia,
schizoaffective disorder and bipolar disorder. We aim to use it primarily
to describe our progress for families which have participated in our
studies. We would also like to help mental health consumers and their
families by including a question-and-answer column. In this regard, we
hope to receive questions from our readers. We are also open to other
suggestions for improvement.
We have chosen "Concordance" as our title because of our desire
for agreement. While almost everyone is in agreement about our need to
know more about the causes of serious psychotic illnesses, there has been
less agreement about what is established fact. We hope through our
research to help establish consensus in this field. In order to do so,
we rely on the kind help of several groups to increase participation in
our studies - family support groups, clinicians, and most important,
individuals with illnesses. We could not achieve what we have without the
aid of these wonderful people. Our hope is that our discoveries will
eventually lead to better treatments and possibly prevention of
schizophrenia.
What is known about the causes of schizophrenia?
The widespread disagreement about causes has been alluded to
above, but almost all concerned people agree that illnesses like
schizophrenia can cluster in some families. This may be due to shared
inherited factors and / or shared environments. It is our belief that the
clustering in families, and indeed the causation of these illnesses in
general, are due to interactions between inherited and non-inherited
(environmental) factors. In support, it is widely accepted that among
pairs of identical twins with one ill twin, the second of the pair is not
invariably doomed to be ill. Thus, even among individuals who share
virtually all their genetic material (and a good deal of their
environment), the chances of falling ill are not identical. The
difference in risk of illness among the well and ill identical twins is
likely to be due to differences in interactions between their inherited
factors and their respective environment.
Another neglected area of research is the likelihood of
protective inherited and non-inherited factors. Indeed, the differences
in risk of illness among identical twins could equally be explained due to
such factors. We are keen to pursue these possibilities.
How do we find the causes?
Since the number of possible causative
environmental factors is enormous, we have chosen to work first with
inherited factors. We realize that such factors may not by themselves
fully explain causation. Rather, they may be predisposing risk factors,
in the same way that smoking predisposes to lung cancer. Once we have
identified inherited predisposing factors, we hope to understand how they
interact with non-inherited factors. Our initial study of inherited
factors is comprised of two parts, one that compares well family members
with those affected with schizophrenia, and one that compares pairs of ill
siblings with each other. In view of the enormous number of possibilities
(the number of genes in any human being are estimated at 1,00,000), it is
necessary to survey a large number of participants.
To achieve our goal of concordance about causes, we wish to
conduct our studies among a variety of ethnic groups. Hence, the study is
being conducted in the United States, India and Canada. We are also
collaborating with scientists in Singapore and Sweden. Our goal is to
recruit 600 families in the USA alone over the next five years- a large
task, but one we are confident of achieving with your help.
How can you help us learn more?
We are currently looking for families to help us learn more about
the causes of schizophrenia. Individuals anywhere in the US are welcome to
participate. The study requires help from the person with schizophrenia,
schizoaffective disorder or bipolar disorder. In addition, the
participation of one or both parents, or an ill sibling is required. All
participants need to give a small sample of their blood, and provide some
information. This can be done wherever is most convenient for you. All
information is strictly confidential.
Progress to date
We have already enlisted the co-operation
of over 200 families for
our research. Most of these families live in Western Pennsylvania, West
Virginia and Ohio. Approximately the same number of families have offered
to participate, and we are in the process of interviewing them. We have
received help from over 30 families in India. While these numbers are
encouraging, we need to continue our survey apace. To this end, we are in
the process of hiring more research associates in these regions. Many of
our staff members belong to family support groups organized by the
National Alliance for the Mentally Ill (NAMI). We hope thus to share our
expertise and information with the communities we receive help from.
We have also begun laboratory analysis of blood samples. We have
identified two inherited factors which may be involved in the causation of
schizophrenia: the dopamine D3 receptor gene and the HLA DQB1 gene. We
are pursuing these clues carefully.
Our research is funded by the Federal Government, through the
National Institute of Health. We have also received support for our work
in Canada from the Stanley Foundation.
