FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a multipass transmembrane protein that is expressed in joints and other tissues and controls pyrophosphate levels in cultured cells. Progressive ankylosis-mediated control of pyrophosphate levels has been suggested as a possible mechanism regulating tissue calcification and susceptibility to arthritis in higher animals. Mutations in this gene have been associated with autosomal dominant craniometaphyseal dysplasia. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygous mutant animals exhibit joint stiffness due to increased calcium deposits in calcified cartilages and die prematurely. Hyperostosis of craniofacial bones and the mandible has been reported in other mutants as well. [provided by MGI curators]
