title: A primary expression map of the chromosome 15q15 region containing the recessive form of limb-girdle muscular dystrophy (LGMD2A) gene.
abstract: Previous genetic and physical studies of LGMD2A, an autosomal recessive form of limb-girdle muscular dystrophy, have led to the establishment of a 10-12 Mb YAC contig encompassing the morbid locus. In order to progress toward the identification of the gene involved in LGMD2A, a primary transcription map of this genomic region was generated. The direct cDNA selection strategy was used with three YACs covering the candidate region and two different muscle cDNA libraries. Seventeen transcription units were identified among 171 cDNA fragments analysed. Five sequences corresponded to known genes, and twelve to new ones. They were characterized for their sequences, physical positions within the YAC contig, and expression patterns. Among those specifically transcribed in muscle, the calpain gene is a good positional and functional candidate for LGMD2A.
