MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Mutations in this gene lead to tuberous sclerosis complex. Its gene product is believed to be a tumor suppressor and is able to stimulate specific GTPases. The protein associates with hamartin in a cytosolic complex, possibly acting as a chaperone for hamartin. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygous null mutants exhibit liver hypoplasia, open neural tube, thickened myocardium and die by embryonic day 9.5-12.5. Heterozygotes develop renal cystadenomas, liver hemangiomas (sometimes resulting in fatal bleeding) and lung adenomas. [provided by MGI curators]
