MGI Phenotype Strain: 5432376
FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This locus encodes a protein that is likely secreted and may function in hematopoiesis. A mutation at this locus has been associated with amelogenesis imperfecta and gingival hyperplasia syndrome. Alternatively spliced transcript variants have been identified. [provided by RefSeq, Aug 2011]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit abnormal ameloblast morphology, disrupted dental enamel formation in both incisor and molar teeth, abnormal kidney morphology, disseminated calcifications of muscular arteries, and intrapulmonary calcifications. [provided by MGI curators]
