- Clinical neuromuscular expertise, patients and geographical region:
The Neuromuscular Division from the Clinical Hospital of Ribeir茫o Preto (HCFMRP-USP, ) is one of the most recognized referral centres for diseases affecting the peripheral nervous system in Brazil. We are based in the countryside of S茫o Paulo State and provide specialized assistance across a catchment area of over 5 million people. Our Hospital is fully maintained by the Public National Health System (SUS). We are committed to provide clinical care, teaching and research to our community. HCFMRP-USP is linked to the Medical School (FMRP, ) from the University of S茫o Paulo (USP, ) and is the primary training centre for neurologists with specific interests in acquired and genetic neuromuscular disorders in South America. We provide both adult and paediatric care, with over 30 neurologists managing over 8,000 outpatient visits per year. We provide a renowned academic research program in Neurology and Neuroscience where relevant and important research is undertaken.
- Genetics and preclinical science expertise and facilities:
Our laboratories perform a significant number of molecular diagnostic tests for nucleic acid targets, tandem repeats and copy number variations every year. Tests included are for specific neurogenetic disorders including the common forms of hereditary neuropathies, recessive and dominant forms of ataxias, mitochondrial DNA abnormalities, motor neuron disease and myopathies. Our laboratory has a well-established collaboration with national and international institutes for genomic medicine. The PI of the project, Professor Marques, is one of the pioneers in Brazil of molecular analysis in neurogenetic disorders: he has contributed decades of research to its development and implementation in clinical practice all over the country, including provision of tests for remote areas.听
- Summary of current research programmes:
Our group鈥檚 primary research interest is to evaluate the epidemiology and the genetic variability of patients with hereditary neuropathy, ataxia, HSP and motor neuron disease from our population. We look for the presence of genetic and environmental modifying factors related to these disorders.
As both leprosy and the demyelinating forms of hereditary neuropathy have abnormalities in the Schwann cell, we also have a specific interest in the electrophysiological characteristics observed in our population with leprosy neuropathy and in the development of protocols with high specificity for its diagnosis, and minimisation of misdiagnosis.
We also have a special interest in mitochondrial diseases, especially those due to respiratory chain involvement. We have a research project for quantification of coenzyme Q10 in different disorders and molecular analysis of nuclear genes and mitochondrial DNA.

- How the new international centre will benefit our research and clinical programmes:
The international centre will offer a unique opportunity to improve the quality our expertise and access to next generation sequencing. Access to these tests is very restricted in Brazil, so the ICGNMD provides an excellent opportunity to evaluate a large number of patients.
The opportunity to work with leading specialists in each of these areas will be the most important benefit. Actively participating in the process of seeing patients, investigating patients and then analysing the genetic basis of their disease will certainly permanently improve our skills as medical doctors and clinical scientists. This is an immeasurable acquisition that will be naturally transmitted to all our fellows.
