Genes affected

P4HA3 (HGNC:30135): (prolyl 4-hydroxylase subunit alpha 3) 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. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2014]

The c.934C>T (p.P312S) alteration is located in exon 7 (coding exon 7) of the P4HA3 gene. This alteration results from a C to T substitution at nucleotide position 934, causing the proline (P) at amino acid position 312 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
