MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is a transmembrane endopeptidase that belongs to the type II integral membrane zinc-dependent endopeptidase family. The protein is thought to be involved in bone and dentin mineralization and renal phosphate reabsorption. Mutations in this gene cause X-linked hypophosphatemic rickets. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]
PHENOTYPE: Males hemizygous for a null mutation exhibit reduced body size, shortened hindlimbs and tail, osteomalacia, and markedly reduced plasma phosphate levels due to impaired kidney reabsorption. Female heterozygotes exhibit milder symptoms. [provided by MGI curators]
