Clinical neuromuscular expertise, patients and geographical
Our Centre is a basic science research institute; we do not see patients directly. Our clinical collaborators evaluate patients, collect samples (blood and tissue) and send to us.
Genetics and preclinical science expertise and
CSIR-CCMB (http://www.ccmb.res.in/) is a premier research organization involved in multidisciplinary R&D programmes across scientific disciplines of biological science for economic, environmental and societal benefits of mankind. These include; Genomics & Epigenomics, Developmental Biology, Cell & Stem Cell Biology, Ecology & Wildlife Conservation, Structural Biology, Microbes and Biology of Infection. CCMB has excellent research facilities, including; NGS & genotyping, tissue culture, FACS, Transgenic & gene knockout, microscopy, crystallography & NMR, etc. PI of the project has over two and half decade of expertise in the field of human genetics and made pioneering contributions in the field of population and medical genomics.
Summary of current research programmes
Thangaraj's studies, for the first time, provide evidence that the contemporary Indian populations descend from two divergent groups - Ancestral South Indians, and Ancestral North Indians (Nature, 2009) - who have admixed during the past 2,000 - 4,000 years, and for the last 2,000 years almost all populations have been practicing endogamy (American Journal of Human Genetics, 2013). Subsequently, he demonstrated that practice of endogamy had led to high frequency of population-specific recessive disease in India (Nature Genetics, 2017). In addition, he has mapped several novel genes that are associated with neuromuscular disorders of mitochondrial origin, cardiovascular diseases and male infertility.

How the new
international Centre will benefit research and clinical programmes:
i. Clinicians, who perform clinical diagnosis of neuromuscular disorders of mitochondrial origin are very few in the country. This project would offer extensive training to the clinical fellows, who would bring the expertise to India.
ii. Enable the establishment of new pipeline NGS data analysis.
iii. Most of mutations that are associated with specific phenotype in rest of the world are most often absent in India and vice versa. This collaboration would help in sharing phenotype/genotype data between centres for better understanding of ancestry and disease.
iv. Most importantly, we envisage that this initiative will pave the way for long-term collaborations.
