Abstract:

Miyoshi myopathy (MM) and limb-girdle muscular dystrophy subtype 2B (LGMD2B) map to the same region on chromosome 2p13. To facilitate the cloning of the defective gene causing these two diseases, we used a combination of chromosome walking and expressed sequence tag (EST) screening and identified 864 P1-derived artificial chromosomes (PACs) whose inserts map to the MM/LGMD2B candidate region and surrounding areas. Among them, 139 are from a chromosome 2-specific PAC library and 725 are from a total genomic PAC library. A 3-Mb contig spanning the candidate region for MM/LGMD2B was assembled. This contig contains 200 PACs, 10 known genetic markers, 5 new polymorphic markers, 57 sequence tagged sites (STSs) generated from PAC end fragments, and 4 random STSs. In addition, we mapped 24 ESTs to this contig and excluded 37 ESTs from the contig, thus eliminating them as candidate MM/LGMD2B genes. The high-resolution, sequence-ready PAC contig for the MM/LGMD2B region provides a backbone for the identification of the disease gene(s) and for clarification of the relationship between the two diseases.
