Enables alpha-1,4-glucosidase activity. Involved in glycogen catabolic process. Predicted to be located in lysosome. Human ortholog(s) of this gene implicated in congenital sucrase-isomaltase deficiency and glycogen storage disease II. Is an ortholog of human MGAM (maltase-glucoamylase).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
