Neurobiology Research Centre

Clinical neuromuscular expertise, patients, and geographical region: NIMHANS (http://www.nimhans.ac.in/) is an institute of national importance for patient care and academic pursuit in the frontier area of mental health and neurosciences. NIMHANS caters to patients from all over India, particularly from South India, and neighbouring countries. A committed team of neurologists with years of expertise routinely handle neuromuscular disorders. Over one hundred patients with mitochondrial disorders and inherited neuropathies undergo thorough clinical evaluation followed by electrophysiology and imaging annually. A speciality clinic for neuropathies is run every week for providing comprehensive care including rehabilitation measures. A specialty clinic for patients with mitochondrial disorders is under way.

Genetics and preclinical science expertise and facilities:
NIMHANS has several basic science departments. The department of Neuropathology, the only one of its kind in the country with full-time experienced and dedicated neuropathologists offers comprehensive and advanced diagnostic services in muscle and peripheral nerve disorders, mitochondrial disorders, among others and has facilities for ultrastructural studies. NIMHANS has the Neurobiology Research Centre (http://www.nimhans.ac.in/neurobiology-research-centre-nrc), a core research facility with 18 well-equipped state-of-the-art labs including the Neuromuscular Laboratory which is the research arm of the department of Neuropathology. It houses the 'myo-bank', and has the expertise and infrastructure for sequencing, respiratory chain complex assays, western blots, immuno-diagnosis, cell culture work, etc.

Summary of current research programmes:
Work at NIMHANS in the last decade has created an effective platform for research in the field of mitochondrial disorders and inherited neuropathies. Our centre is one of the first in India to identify several novel variants in mitochondrial DNA, evaluate children and adults with deficient respiratory chain complex activity, explore nuclear-mitochondrial intergenomic communication disorders, characterize POLG-related disorders, carry out focused exome sequencing, study the utility of FGF-21 and initiate generation of cybrid models. Two large cohorts of inherited axonal and demyelinating neuropathies have been analysed for the presence of abnormalities in common genes viz MFN2, PMP22, MPZ and GJB1.

How the new international centre will benefit research and clinical programmes:

Research benefit:
This International Centre will enable the detection of population-specific genetic variations among patients with mitochondrial disorders and hereditary neuropathies as well as comparison across continents through common pipelines. Further, this will set platform for future collaborative studies in this field including functional characterisation.

Clinical benefit:
Establishing genetic diagnosis will end diagnostic odyssey and enable customised care. This program will generate a cadre of fellows and scholars with the necessary expertise to carry forward clinical and research work in a sustainable manner. It will also facilitate setting up registries and trial-ready cohorts and facilitate policy planning in India.
