MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a dual-specificity phosphatase that associates with polyribosomes. The encoded protein may be involved in the regulation of glycogen metabolism. Mutations in this gene have been associated with myoclonic epilepsy of Lafora. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2008]
PHENOTYPE: Mice homozygous for a targeted null mutation exhibit behavioral deficits, ataxia, myoclonus epilepsy, and widespread degeneration of neurons in the presence of only a few small Lafora inclusions, providing a putative mouse model of human Lafora disease. [provided by MGI curators]
