Bimonthly Newsletter - October/November 2007  
 
The Telethon has become France’s major fund-raising event with a record 106 696 532 euros raised in 2006! This year, the AFM presents the 21st annual Telethon on 7th-8th December 2007. Behind the appeals and wide array of entertainment, the goal of the Telethon is to raise funds to support the AFM’s research programs and services for people with neuromuscular diseases and to spread public awareness of rare genetic disorders. Donations have helped research into gene-based therapies, the best hope for curing thousands of currently incurable diseases. Donations also go to promoting the understanding, the diagnosis and management of diseases. The Telethon has helped improve the life of patients with neuromuscular diseases and has changed the society’s perception of these debilitating disorders. Each Telethon represents a great step forward in the battle to conquer devastating diseases.
 
The success of the 21st edition of the Telethon depends on you! Your donations will help accelerate research progress and raise patients’ hopes.

Clinical Trials

 
The Institute of Myology was established to fill the needs of the AFM, of patients and their families and to set up in public hospitals a reference centre that includes medical specialists, basic and clinical research teams and education curriculum on muscles and their pathologies. The AFM’s mission is to stimulate innovative clinical research by helping conduct clinical trials and by financing part, or all of them. Each year the AFM launches a call for proposals dedicated to the development of therapeutics. This program may concern the development of therapeutic products, or preclinical and clinical trials. All projects are evaluated by the Scientific Council. In order to provide an impetus to clinical trials, the AFM has created a service whose role is to identify innovative scientific strategies, stimulate and monitor projects. For example, as a result of studying the potential of cell therapy in FSHD, the AFM received several preclinical research proposals in this fi eld. The AFM’s role then consists in helping those teams who wish to elaborate their projects before they are submitted to the Scientific Council during the call for proposals period.
The AFM is funding nearly 40 clinical trials that are either in preparation or in progress, including about twenty trials at the Institute of Myology which concern both the natural history of genetic muscular disease and pharmacological, cell, gene and enzyme therapies as well as effort retraining.
Besides the trials investigated directly by teams from the Institute of Myology, the AFM or Généthon, the technological and scientific platform of the Institute is recognised by well-known organisations (NIH; Genzyme) which have chosen it for some of their trials.

 
Development of a French isometric strength normative database

 
Loss of muscle strength is one of the key features in diseases such as amyotrophic lateral sclerosis (ALS) and Duchenne muscular dystrophy (DMD) and accurate evaluation of muscle strength is crucially important. In this article, Dr. Jean-Yves Hogrel from the Institute of Myology and his colleagues describe the development of a normative database for isometric strength measured by quantitative muscle testing (QMT) for a French adult population. The study included 315 healthy men and women from four clinical centres treating patients with neuromuscular disorders. Strength measurements for 14 muscle functions (13 bilaterally and neck flexion) were performed. In 86% of patients, the right side was dominant and significantly stronger (P<0.05) for all muscle functions except hip flexion and extension, knee flexion and shoulder internal rotation. A predicted strength value for each muscle group could be computed for a patient of any age, sex and height. Compared to published normative data from the U.S. population, with the exception of hip extension, significantly lower values were observed in the French population. The predictive values deduced from the French regression models were also lower than the American predictive values. This database will allow objective evaluation of patients with respect to these normative data, assessment of the degree of their neuromuscular deterioration and collection of information on the clinical course of the disease. Furthermore, composite scores can be estimated in therapeutic trials to follow a global index of strength.

Redefining the clinical spectrum associated with dystroglycanopathy genes

 
Defects in glycosylation of alpha-dystroglycan are associated with several forms of muscular dystrophy, often characterized by congenital onset and severe structural brain involvement, collectively known as dystroglycanopathies. Six causative genes have been identified in these disorders: POMT1; POMT2; POMGnT1; fukutin, FKRP and LARGE. The increased availability of mutation analysis in patients with a dystroglycanopathy has consequently led to the discovery of a range of phenotypes resulting from mutations in FKRP. However, there is no data concerning the frequency of involvement or the genotype-phenotype relationships for the other five genes in a large and unbiased population. In this study, the authors have systematically screened a large population of 92 unrelated individuals with a dystroglycanopathy phenotype for mutations in POMT1; POMT2; POMGnT1; fukutin and LARGE genes. Mutations were observed in 34% of these patients. Mutations in the FKRP gene had previously b een excluded. Mutations in POMGnT1 and fukutin were associated with a wider than reported spectrum of clinical severity. The majority of patients with POMT1 and POMT2 mutations have evidence of central nervous system involvement. Only one patient presented a mutation in the LARGE gene. In decreasing order of prevalence, mutations in the glycosyltransferase genes were as follows: POMT2; POMT1; POMGnT1; fukutin and LARGE. The data presented in this paper increase the clinical spectrum of disorders associated with mutations in the known glycosyltransferase genes.

 
Identification of six novel POMGnT1 mutations

 
Muscle-eye-brain disease (MEB; OMIM 253280) was first described in 1977 in Finland, where it is enriched because of founder effect and genetic isolation. MEB is now known to occur throughout the world, but Finland remains the country with the largest group of MEB patients. It is an autosomal recessive disorder characterized by congenital muscular dystrophy, brain malformation and ocular abnormalities. MEB is caused by mutations in the protein O-linked mannose ß1,2-N-acetylglucosaminyltransferase 1 (POMGnT1) gene. To date, 28 different POMGnT1 mutations have been identified with a diverse clinical spectrum. In this paper, Dr. Ute Hehr and her colleagues describe the clinical, neuroradiological and molecular genetic findings in nine MEB patients from eight independent families of various ethnic origins. The authors aimed to further characterize the spectrum of identified human POMGnT1 mutations and to investigate a possible genotype-phenotype correlation. The age at the ti me of clinical examination varied between 3 months and 16 years. Psychomotor and mental development indicated moderate to severe global retardation. At birth, all patients presented a severe muscular hypotonia with distinctly elevated CK values. Ophthalmologic findings revealed a wide array of abnormalities in all patients, resulting in severe visual impairment, the most frequent being sever myopia. Out of five cases, prenatal ultrasound data revealed a hydrocephalus in four patients. The most prominent and consistent feature observed on cerebral MR images was marked alterations of the white matter, including hypoplasia of the brainstem with a characteristic flattening and kinking of the pons. Hydrocephalic changes of varying degree and thinning of the corpus callosum were also observed in this patient cohort. Concerning molecular genetic findings, three previously reported and six novel POMGnT1 mutations were identified. The combined data from this study allowed the authors to conclude that there is no genotype-phenotype correlation for POMGnT1-confirmed MEB patients and that additional environmental and/or genetic factors may contribute to the observed clinical variability of POMGnT1-associated phenotypes.
US non-profit formed to further gene therapy for orphan diseases

 
Asklepios BioPharmaceutical, Inc., (AskBio) has announced the creation of the Chapel Hill Project, a non-profit organisation created to further development of cell and gene therapies for orphan diseases. Askbio will provide the Chapel Hill Project with access to its Biological NanoParticle (BNP) and Self-Complementary Vector technologies with no up-front cost. The Chapel Hill Project will make this technology available to researchers for use in developing novel treatments for orphan disease indications. The Chapel Hill Project hopes to eventually serve as a depository for intellectual property that can be used for the development of cell and gene therapies for orphan diseases with other companies contributing the use of their DNA-based technologies in order to speed the advancement of orphan disease therape utics to the market. Recombinant adeno-associated virus (rAAV) has become a successful gene-delivery vector for a multitude of targets due to its "non-pathogenic properties and absent immune response, ability to maintain efficient and long-term expression, and ease of genetic manipulation". AskBio has developed a library of rAAV Biological Nano Particles.
 
   Online report : T Voit at the WMS congress

 
image
The 12th International Congress of the World Muscle Society (WMS), was held in Giardini Naxos in Sicily from 17 to 20 October.

 
The congress was dedicated to three groups of neuromuscular diseases: metabolic myopathies, congenital muscular dystrophies and congenital myopathies. As usual, the final day was devoted to therapeutic approaches. Thomas Voit, Scientific Director of the Institute of Myology and member of the WMS programme, shares his impressions of the event.
 
As a member of the WMS programme committee, were you fully satisfied with the congress, in terms of the organisation or scientifically?
I wouldn’t say that I was 100% satisfied but that’s related to my character. On the whole, the congress went very well, especially given the number of participants. There was a particular problem during the poster session, which was inconvenienced by the excessive number of both people and posters. Next year, we will improve or at least change the way posters are presented. This is part of the various changes that we would like to implement next year so that the WMS congress regains its more intimate character and thereby stimulates collaboration.

  • 2nd International conference on trends in cellular and molecular biology
    Jan 5-7 2008, New Delhi, India
Cell and molecular Biology have made tremendous strides over time. Inputs from physical scientists especially in the area of structural biology has added a great deal of information to our knowledge base of interrelationship between structure and function. Structure can be manipulated to modulate a function or create a new function. In today's post genomic era proteomes are well analysed thanks to the advent of several kinds of mass spectrometers. However, in spite of these advances we have only partial understanding of complex processes like cell growth, cell cycle, cell proliferation, cell differentiation inter- and intra-cellular trafficking and apoptosis. The International Congress on Cellular and Molecular Biology will focus on life processes that are least understood.

Press Release

 
10/10/2007 - Trophos starts phase Ib clinical trial of TRO19622 in Spinal muscular atrophy
Trophos SA, a biopharmaceutical company specializing in the discovery and development of drugs for neurological disorders, announced that the company has begun enrolling Spinal Muscular Atrophy (SMA) patients in a Phase Ib clinical trial of its lead product, TRO19622. The clinical trial will involve 20 type 1b-3 SMA patients aged between 6-25 years of age and will assess the pharmacokinetics and safety of drug product after administration of single and multiple doses, once-daily, by the oral route. The study is being conducted at three centres in France.
The clinical program in SMA is supported by the Association Française contre les Myopathies (AFM), through a strategic partnership begun in 2000.
Thanks to Téléthon donations, over the last 7 years Trophos has received decisive financial support from the AFM for this project. Now, barely four years after the identification of a candidate molecule, a clinical trial in hum ans is underway. This again shows how a patient association can play a leading role in promoting drug development.

Glossary of terms associated with neurolological disorders

Amniocentesis:
Removal of a sample of amniotic fluid for prenatal testing. Cells from the unborn child can be extracted from the fluid which surrounds it in the womb and tested for certain abnormalities.
Autosomes:
All the chromosomes other than the X and Y (the sex chromosomes) are known as autosomes. Autosomal inheritance means that an abnormal gene can affect either sex.
Cell:
The basic structural unit of all living organisms. The cell is surrounded by a membrane. Inside the cell is a structure called the nucleus. The nucleus contains DNA arranged into chromosomes.
Cell Therapy:
See Myoblast transfer
Chorionic villus sampling (also known as CVS):
Removal of chorionic villi for prenatal testing. The chorionic villa are cells situated on the wall of the uterus (womb) which form the early placenta (afterbirth). They have the same genetic make-up as the unborn baby and can be tested to detect certain abnormalities.
Chromosomes:
Sausage shaped bundles in the cell nucleus made of a very long thin strand of the chemical molecule DNA coiled upon itself many times. Humans have 46 chromosomes (23 pairs) in most cells of their bodies. The sex cells (the unfertilized egg and sperm) contain only 23 unpaired chromosomes each. Fertilization of a 23-chromosome egg by a 23-chromosome sperm produces a new 46-chromosome cell which grows into a new individual. In this way one half of each chromosome pair is inherited from each parent.
Congenital:
Present at birth or soon afterwards.
Contractures:
Shortening of muscles or tendons which prevents the associated joints from moving freely
Deletion:
The loss of a bit of genetic material from a chromosome or gene.
DNA - Deoxyribonucleic Acid:
The chemical of which genes are made. it contains coded information arranged in a linear sequence. Each cell's chromosomes contain about two metres of DNA yet it is so thin that it is barely visible even with the most powerful microscope. If all the DNA in a human body were stretched end to end it would be long enough to reach the moon and back about 10,000 times.
Dominant:
In dominant inheritance if one of a pair of genes is altered the individual possessing that gene will show signs of the relevant disorder. In any pregnancy there is a 50 percent chance that he or she will pass the altered gene on giving rise to a child who is also affected.
Duplication:
Where a part of a chromosome or gene is duplicated.
Enzyme:
A protein that triggers chemical reactions.
Gene therapy:
A potential method of treatment for genetic disorders which involves making correct copies of the gene in question and then transporting them into the cells of the body.
Genes:
The coded instructions that govern the make-up of every human being. Genes are made of DNA. Each gene carries instructions for the production of a specific protein. Genes usually come in pairs one inherited from each parent. They are passed on from one generation to the next and are the basic units of inheritance. Alterations in genes (mutations) which lead to abnormal function of the corresponding protein can cause inherited disorders.
Genetic counseling:
information and support provided by a specialist usually a doctor or nurse to people who have genetic conditions in their families or who are concerned about the future possibility of genetically transmuted conditions.
Genetic disorders:
Conditions which result from alterations in the genetic make-up of an individual. They may be the consequences of defects in single genes or in whole chromosomes parts of which may be lost, duplicated or misplaced: or may result from the interaction of multiple genes and external factors.
Genetic markers:
Harmless variations in the DNA which lie close to the site of a disrupted gene which may be used for tracking the condition through a family.
Linkage studies:
These are tests carried out on various family members to establish which is the crucial bit of genetic code causing a particular condition in that family.
Immune response:
The response by the body to "foreign" material (transplant or infection).
Manifesting carrier:
A female carrier of an X-linked condition who shows symptoms.
Muscle fibre:
The basic unit of muscle tissue formed by the fusion of groups of muscle cells.
Mutation:
When a gene is changed or altered in some way this is called a mutation. Mutations can be passed on to subsequent generations.
Myoblast transfer:
A potential method of treatment for Duchenne muscular dystrophy which involves the transplantation of billions of healthy donor cells into muscle. This is sometimes known as cell therapy.
Nucleus:
Structure in the centre of each cell which contains the chromosomes with their genetic material.
Orthoses:
Devices or aids to prevent, correct or control deformities.
Preclinical diagnosis:
Diagnosis of a genetic disorder before there are any symptoms of that disorder.
Prenatal:
Literally, before birth.
Prognosis:
Predicted course and outcome of a disorder.
Recessive:
A form of inheritance where a genetic defect causes little or no outward effect unless it is present in both of a pair of genes and has therefore been inherited from both parents. If a person has inherited one altered gene and one normal gene he or she will not be affected but will be a gene carrier. If two carriers of the same altered gene have children in each pregnancy there is a 25 percent chance that the child will inherit two copies of the altered gene and will be affected.
Sex chromosomes:
The X and Y chromosomes determine the sex of an individual. Females have two X chromosomes: males have an X and a Y chromosome.
Ultrasound:
This is a technique which uses reflected sound waves to see a hidden object. it is now widely used in medicine for example to obtain images of muscle structure and internal organs or of the unborn child.
X-linked:
A form of inheritance where the gene in question lies on the X chromosome. X-linked genes can be dominant but are usually recessive. Girls who carry an altered gene are usually not affected since they have a second normal copy of the gene but they can pass the affected gene on in 50 percent of their pregnancies. Boys who have only one X chromosome do not have a second normal copy of the gene so they will be affected by the disorder in question. They will pass on the altered gene to all of their daughters who will be carriers but to none of their sons.
