"Indian science in genomics has been able to
place itself on the global map"
-Dr Samir K Brahmachari, Director General, CSIR, Delhi
These are exciting times for Indian science. India is all set to play host
to the 13th human genome meeting in September this year. The excitement is
already palpable since it not only happens to be the 20th anniversary of the
Human Genome Organization (HUGO), but it is for the first time that the Human
Genome Meeting is being held in India. India has also submitted data on the
Indian genome variation that has been published in the Journal of Genetics,
(Vol.87, No.1, April 08) . In a chat with Dr Samir K Brahmachari, Director
General, CSIR, BioSpectrum finds out more about HUGO and the buzz about the
human genome meeting in India. Incidentally, Dr Samir Brahmachari will be
delivering the special address during the CEO conclave at Bangalore Bio 2008 on
this
topic. Excerpts:
What is the objective of HUGO and when was
it formed?
The Human Genome Organization was formed at the very
beginning of the human genome project with an idea that this will be the forum
where information will be shared across the world without any restriction of
geographical boundaries. This is an organization by the scientists, for the
scientists all across the world, in order to disseminate the human genome
information to the world, to make available the human genome sequence in the
public domain so that everyone has equal access to it. HUGO has played a very
important role in not only making the human genome sequence open source and
publicly available, but also making the knowledge available and also addressing
the ethical, social and legal issues that would concern the society. As per its
policy, five percent of its fund utilized for research is used to address
ethical, legal and social implications of the human genome sequencing that were
understood as early as the 1990s.
The human genome project was initiated in the late 1980s
under the funding of the Department of Atomic Energy (DAE). HUGO was formed as
an organization in Switzerland wherein HUGO US and Moscow were associated
members. In 1990, I was the one of the early members elected to HUGO along with
Prof. Notani of BARC from India with 100 odd scientists. The original objective
of HUGO was to coordinate the mapping of the genome. So the human genome mapping
workshop was initiated. And it was only in the late 1990s when the mapping was
completed, that the Human Genome Meeting was actually started . So in this
series, we shall be hosting the 13th Human Genome Meeting in India in Hyderabad
from September 27-30, 2008.
Please elaborate on the Human Genome
Meeting (HGM) being held for the first time in India.
In the beginning HGM was held for a year in Europe and then
in the US. It was only in 2002 that the HGM came to China for the first time.
This was because China participated from the developing world in the human
genome sequencing project from 1999-2001. Japan has been a major player along
with the US and Europe and hence recognizing this, the meeting came back to Asia
again, in 2005 in Japan. This is the third time the meeting is coming to Asia
and this time it is India. We have chosen Hyderabad for the meeting, since it
has one of the best convention centers in the country where a meeting of such a
global stature can be held.
How do you see the significance of the
meeting coming to India?
This signifies the contribution that India has made in
genomics by developing the Indian genome variation landscape. This is something
unique because this is the first time that 55 populations across a country have
been mapped for various gene risk alleles. This signifies that Indian science in
genomics has been able to place itself on the global map. Accepting to hold the
meeting in India and directing me to chair is the recognition of this.
What are the key features of the meeting?
We are expecting a participation of 500 students in the
meeting. We are organizing special satellite meetings, a "Know your
Genome" meeting for students to make them aware of the human genome, and a
clinical genomic workshop for clinicians amongst others. The meeting also aims
to address the ethical and legal issues associated with the human genome. We are
also thinking of a session on the business of genomics and new biology for young
entrepreneurs. There will be an exhibition of new instruments and technologies
as well as many presentations on technological aspects as well. It will be a
platform to showcase the Indian industry to the world. Besides, people will get
to see and listen to the who's who of genomics, such as Craig Venter.
What are your expectations from the
meeting?
When I was young and molecular biology had just come, we
hardly had any resources, capabilities or access to information. Today this new
biology is bringing to the fore the champions working at the frontiers. I want
to expose Indian scientists to them and make them realize that things are not
difficult for us and that India is no longer behind. This would enable them to
think bigger.
The Indian genome variation study uses
disease markers instead of neutral markers. Kindly elaborate.
Certain areas of the genome are neutral under natural
selection, so if one wants to know who is related to whom and how are different
populations related, neutral markers would provide the requisite information.
But we realized that our objective was to find how various disease gene risk
alleles are distributed in the population, which is why we used disease markers.
What are the advantages of using disease
markers in the study?
This helps us get background control information so that we
know what is the general variability across the population, if a disease is high
risk or low risk and thus helps us address the stratification problem. Second,
it also helps us understand how the drug responds across different populations,
to see how some drugs which may not be working in the Japanese population may
not be working in the North-East region but might work in the southern region of
India. Thereby India can have a low cost drug in the market using
pharmacogenomic principles. What it demonstrates is that irrespective of using
markers, which are disease linked markers, we are able to cluster the Indian
population into four major clusters. It has further been revalidated. It is
interesting to note that both the neutral marker and the disease markers could
reasonably segregate the population. The study also found that despite
linguistic variability, there is enormous genetic heterogeneity across the
Indian population.
