Dystrophin Related Protein is the recently identified protein product of a large autosomal transcript, showing significant similarity to dystrophin at the carboxyl terminus. Dystrophin related protein and dystrophin share a similar abundance and molecular weight, however, they differ both in their tissue distribution and expression in Duchenne/Becker(More)
We present here the clinical, molecular and biochemical findings from 238 limb-girdle muscular dystrophy type 2A (LGMD2A) patients, representing approximately 50% (238 out of 484) of the suspected calpainopathy cases referred for the molecular study of the calpain 3 (CAPN3) gene. The mean age at onset of LGMD2A patients was approximately 14 years, and the(More)

Virus-specific cytotoxic T lymphocytes (CTL) which kill virus-infected cells are thought to be a major host defence against viral infections. Here we report the existence of human immunodeficiency virus (HIV)-specific CTL in persons infected with this virus, the aetiological agent of AIDS (acquired immunodeficiency syndrome). Recombinant HIV-vaccinia(More)
The sarcoglycan complex is involved in the etiology of four autosomal recessive limb-girdle muscular dystrophies (LGMD2C-F). A missense mutation (T151R) in the beta-sarcoglycan gene on chromosome 4q12 has been shown to cause a mild form of LGMD2E in 11 families from a Southern Indiana Amish community sharing a common haplotype. We now report that two sibs(More)
X-linked recessive Duchenne muscular dystrophy (DMD) is caused by the absence of dystrophin, a membrane cytoskeletal protein. Dystrophin is associated with a large oligomeric complex of sarcolemmal glycoprotein. The dystrophin-glycoprotein complex has been proposed to span the sarcolemma to provide a link between the subsarcolemmal cytoskeleton and the(More)
The gene that is defective in patients with Duchenne and Becker muscular dystrophy consists of about 60 short exons scattered along a gigantic DNA region that spans some 2 megabase pairs. The encoded protein, dystrophin, was recently characterized as a component of muscle intracellular membranes of low abundance. The dystrophin messenger RNA is difficult to(More)
Primary adhalin (or alpha-sarcoglycan) deficiency due to a defect of the adhalin gene localized on chromosome 17q21 causes an autosomal recessive myopathy. We evaluated 20 patients from 15 families (12 from Europe and three from North Africa) with a primary adhalin deficiency with two objectives: characterization of the clinical phenotype and analysis of(More)
Duchenne progressive muscular dystrophy is a lethal and common X-linked genetic disease caused by the absence of dystrophin, a 427K protein encoded by a 14 kilobase transcript. Two approaches have been proposed to correct the dystrophin deficiency in muscle. The first, myoblast transfer therapy, uses cells from normal donors, whereas the second involves(More)
Duchenne muscular dystrophy (DMD) is an X-linked recessive genetic disorder for which the biochemical defect is as yet unknown. Recently, two cloned segments of human X-chromosome DNA have been described which detect structural alterations within or near the genetic locus responsible for the disorder. Both of these cloned segments were described as tightly(More)
We have found that assembing the reaction mixture at a temperature greater than the annealing temperature improved both product yield and specificity of PCR. When reactions were maintained at 70°C in a dry heating block during addition of denatured samples to aliquotted reagent master mix, a reproducible increase in product yield was observed compared to(More)
