Genes affected

P4HA2 (HGNC:8547): (prolyl 4-hydroxylase subunit alpha 2) This gene encodes a component of prolyl 4-hydroxylase, a key enzyme in collagen synthesis composed of two identical alpha subunits and two beta subunits. The encoded protein is one of several different types of alpha subunits and provides the major part of the catalytic site of the active enzyme. In collagen and related proteins, prolyl 4-hydroxylase catalyzes the formation of 4-hydroxyproline that is essential to the proper three-dimensional folding of newly synthesized procollagen chains. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008]

The c.1314G>C (p.E438D) alteration is located in exon 12 (coding exon 11) of the P4HA2 gene. This alteration results from a G to C substitution at nucleotide position 1314, causing the glutamic acid (E) at amino acid position 438 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
