A register based system for gene tracking in Duchenne muscular dystrophy.

چکیده
A total of 102 families with Duchenne muscular dystrophy has been studied with linked DNA polymorphisms as an aid to estimating carrier risks for female relatives. Early work using probes RC8, L1.28, and pXUT23 gave very little clinically useful information because of the high recombination rates between these probes and Duchenne muscular dystrophy and the low proportion of women who were heterozygous. Clinically useful results were obtained using probes 99-6, 754, and particularly pERT87. Examples are given of deductions which can be made using these probes. The importance of a genetic register is stressed as a tool for long term contact with the families and other professionals.

P164: Adeno-Associated Viral Vectors in Duchenne Muscular Dystrophy
Duchenne muscular dystrophy (BMD) is an inherited X-link disease. The incidence of this muscle-wasting disease is 1:5000 male live births. Mutation in the gene coding for dystrophin is the main cause of BMD. Most cases of this disease succumb to respiratory and cardiac failure in 3rd to 4th decades. The slow progression of BMD and recent achievement of gene therapies make it as an appropriate c...

Background Duchenne Muscular Dystrophy (DMD) is a deadly X-linked recessive disorder. This genetic disorder affects 1 among 3,500-5,000 males in the world. The majority of the patients are male, due to the type of inheritance. It affects most of the skeletal, the respiratory, and cardiac muscles, causing these vital organs to contract and eventually mortality.<br...

Background and Objective: Duchenne Muscular Dystrophy(DMD) is a neuromuscular disorder with progressive muscle wasting and weakness. This disease is the consequence of mutations in dystrophin gene located on X chromosome. Inheritance pattern of the disease is gene-dependent recessive with an incidence of one in 3500 alive male newborns. Due to the absence of efficient treatment, detection of fe...

A register of families with Duchenne muscular dystrophy (DMD) in Wales was set up in 1973 and has been regularly maintained ever since. All women at significant risk in these families were offered estimation of their carrier status by creatine kinase and pedigree analysis. A total of 225 of the 512 women tested was assigned a risk of carrying the DMD gene of less than 5%. One hundred and twenty...
