Mutations in this gene are associated with muscle glycogen storage disease. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Sep 2009] Expression Ubiquitous expression in heart (RPKM 40.6), fat (RPKM 17.3) and 23 other tissues See more Orthologs mouse all
