Genes affected
P3H1 (HGNC:19316): (prolyl 3-hydroxylase 1) This gene encodes an enzyme that is a member of the collagen prolyl hydroxylase family. These enzymes are localized to the endoplasmic reticulum and their activity is required for proper collagen synthesis and assembly. Mutations in this gene are associated with osteogenesis imperfecta type VIII. Three alternatively spliced transcript variants encoding different isoforms have been described. Other variants may exist, but their biological validity has not been determined. [provided by RefSeq, Aug 2011]

Collection Method:clinical testing

The P3H1 c.1616A>G, p.Tyr539Cys variant (rs772654104), to our knowledge, is not reported in the medical literature but is reported as uncertain in ClinVar (Variation ID: 536812). This variant is found in the general population with an overall allele frequency of 0.001% ([3/251,136 alleles) in the Genome Aggregation Database. The tyrosine at codon 539 is weakly conserved, and computational analyses (SIFT: damaging, PolyPhen-2: benign) predict conflicting effects of this variant on protein structure/function. Due to limited information, the clinical significance of the p.Tyr539Cys variant is uncertain at this time. -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 539 of the P3H1 protein (p.Tyr539Cys). This variant is present in population databases (rs772654104, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with P3H1-related conditions. ClinVar contains an entry for this variant (Variation ID: 536812). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.1616A>G (p.Y539C) alteration is located in exon 11 (coding exon 11) of the P3H1 gene. This alteration results from a A to G substitution at nucleotide position 1616, causing the tyrosine (Y) at amino acid position 539 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
