FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the prolyl 3-hydroxylase subfamily of 2-oxo-glutarate-dependent dioxygenases. These enzymes play a critical role in collagen chain assembly, stability and cross-linking by catalyzing post-translational 3-hydroxylation of proline residues. Mutations in this gene are associated with nonsyndromic severe myopia with cataract and vitreoretinal degeneration, and downregulation of this gene may play a role in breast cancer. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Dec 2011]
PHENOTYPE: Mice homozygous for a knock-out allele of exon 2 exhibit embryonic lethality between E8.5 and E12.5 with maternal platelets aggregate around the ectoplacental cone. Exon 3 knockouts are viable but mice exhibit reduced hydroxylation of collagen chains, especially in the sclera, leading to eye tissue dysmorphology and progressive myopia. [provided by MGI curators]
