Genes affected

P3H3 (HGNC:19318): (prolyl 3-hydroxylase 3) The protein encoded by this gene belongs to the leprecan family of proteoglycans, which function as collagen prolyl hydroxylases that are required for proper collagen biosynthesis, folding and assembly. This protein, like other family members, is thought to reside in the endoplasmic reticulum. Epigenetic inactivation of this gene is associated with breast and other cancers, suggesting that it may function as a tumor suppressor. [provided by RefSeq, Aug 2013]

P3H3 links:

GPR162 (HGNC:16693): (G protein-coupled receptor 162) This gene was identified upon genomic analysis of a gene-dense region at human chromosome 12p13. It appears to be mainly expressed in the brain; however, its function is not known. Alternatively spliced transcript variants encoding different isoforms have been identified.

The c.68C>A (p.P23H) alteration is located in exon 1 (coding exon 1) of the P3H3 gene. This alteration results from a C to A substitution at nucleotide position 68, causing the proline (P) at amino acid position 23 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
