MGI Phenotype FUNCTION: This gene encodes a lysosomal acid glucosidase that is involved in the degradation of glycogen. The encoded preproprotein undergoes proteolytic processing to generate a mature enzyme that cleaves alpha-1-4 and alpha-1-6 glycosidic bonds of glycogen, maltose and intermediate oligosaccharides within the lysosome. Mice lacking the encoded protein exhibit symptoms similar to human Pompe syndrome such as accumulation of glycogen in cardiac and skeletal muscle lysosomes resulting in reduced mobility and strength. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Nov 2015]
PHENOTYPE: Homozygous inactivation of this gene leads to massive glycogen accumulation in multiple organs, cardiomyopathy, hypoactivity, severe motor disability, profound muscle weakness and wasting, and progressive kyphosis. The age of onset and clinical course ofthe disease appear to be strain-dependent. [provided by MGI curators]
