Characterization and chromosome assignment of the canine gamma-sarcoglycan gene (SGCG) to CFA 25q21-->q23

Mutations in the gene for gamma-sarcoglycan (SGCG) located on HSA 13q12 are responsible for limb girdle muscular dystrophy (LGMD2C) in human. Here we report the cloning of the canine SGCG gene together with its genomic structure and several intragenic polymorphisms. The coding part of the canine SGCG contains seven exons spanning at least 70 kb of genomic DNA. The chromosome assignment of the canine SGCG gene to CFA 25q21-->q23 confirms that the canine syntenic group 10 corresponds to CFA 25 and also supports the findings of human-canine reciprocal chromosome painting.
