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]

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jun 09, 2023	This premature translational stop signal has been observed in individual(s) with osteogenesis imperfecta (PMID: 19088120, 27509835). For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 1258). This variant is present in population databases (rs118203996, gnomAD 0.002%). This sequence change creates a premature translational stop signal (p.Arg368*) in the P3H1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in P3H1 are known to be pathogenic (PMID: 17277775, 18566967, 19088120, 22281939). -
