Genes affected

PLOD3 (HGNC:9083): (procollagen-lysine,2-oxoglutarate 5-dioxygenase 3) The protein encoded by this gene is a membrane-bound homodimeric enzyme that is localized to the cisternae of the rough endoplasmic reticulum. The enzyme (cofactors iron and ascorbate) catalyzes the hydroxylation of lysyl residues in collagen-like peptides. The resultant hydroxylysyl groups are attachment sites for carbohydrates in collagen and thus are critical for the stability of intermolecular crosslinks. Some patients with Ehlers-Danlos syndrome type VIB have deficiencies in lysyl hydroxylase activity. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

This sequence change creates a premature translational stop signal (p.Tyr630*) in the PLOD3 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in PLOD3 are known to be pathogenic (PMID: 30237576). This variant is present in population databases (rs748105435, gnomAD 0.02%). This premature translational stop signal has been observed in individual(s) with clinical features of lysyl hydroxylase 3 deficiency (PMID: 36307859). ClinVar contains an entry for this variant (Variation ID: 225442). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
