    摘要: Disclosed are compositions and methods for aiding in the diagnosis of congenital muscular dystrophy associated with in-frame deletion in the laminin-2 .alpha.2 polypeptide chain in an individual. In a preferred diagnostic method embodiment, an experimental muscle tissue sample is provided from the individual and treated if necessary to render components available for antibody binding. The components of the sample are then separated on the basis of molecular weight. The separated protein components are then transferred to a solid support while maintaining the relative positions established in separation step. The transferred components are then stained with an affinity reagent which is known to bind to a C-terminal domain of the laminin-2 .alpha.2 polypeptide chain. Individual afflicted with congenital muscular dystrophy associated with in-frame deletion in the laminin-2 .alpha.2 polypeptide chain on the basis of positive staining in combination with reduced molecular weight of the laminin-2 .alpha.2 polypeptide chain relative to the wild-type laminin-2 .alpha.2 polypeptide chain. A preferred composition is a nucleic acid probe for the detection of merosin deletion-type congenital muscular dystrophy. The preferred nucleic acid probe is characterized by the ability to bind specifically to a mutant merosin nucleic acid sequence, the mutant merosin nucleic acid sequence comprising a T to C substitution at position 3973 +2 of the consensus donor splice site of exon 25.

    摘要: Disclosed herein are compositions and methods for the detection of primary adhalinopathy. More specifically, disclosed herein are nucleic acid probes which hybridize specifically, under stringent hybridization conditions, to a mutant adhalin gene or the complement thereof, but not to the corresponding region of a wild-type adhalin gene. Also disclosed are methods for the detection of a mutation in the human adhalin gene which is responsible for primary adhalinopathy. Such methods include the use of the nucleic acid probes of the invention for detection of the myopathy by hybridization, as well as detection by direct DNA sequencing techniques.

    摘要: Disclosed herein is a substantially pure nucleic acid sequence encoding a mammalian 43 kDa non-dystrophin component (.beta.-sarcoglycan) of the dystrophin-glycoprotein complex. Also disclosed are immunogenic peptides which, when used to immunize a mammal, stimulate the production of antibodies which bind specifically to the .beta.-sarcoglycan. Mutations in the .beta.-sarcoglycan gene which are associated with autosomal recessive limb-girdle muscular dystrophy are also disclosed. The identification of such mutations enables the design of nucleic acid probes which hybridize specifically to a mutant form of .beta.-sarcoglycan, or the complement thereof, but not to the DNA of the wild-type form of the gene (or the complement thereof), under stringent hybridization conditions. Such probes are useful, for example, in connection with the diagnosis of autosomal recessive limb-girdle muscular dystrophy. In addition, the identification of such mutations enables the diagnosis of autosomal recessive limb-girdle muscular dystrophy through the use of direct DNA sequencing techniques.
