Genes affected

PLOD1 (HGNC:9081): (procollagen-lysine,2-oxoglutarate 5-dioxygenase 1) Lysyl hydroxylase is a membrane-bound homodimeric protein localized to the cisternae of the 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 VI have deficiencies in lysyl hydroxylase activity. Two transcript variants encoding different isoforms have been found for this gene.

This sequence change creates a premature translational stop signal (p.Arg319*) in the PLOD1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in PLOD1 are known to be pathogenic (PMID: 10874315, 21699693). This variant is present in population databases (rs121913550, gnomAD 0.006%). This premature translational stop signal has been observed in individual(s) with PLOD1-related conditions (PMID: 15666309). ClinVar contains an entry for this variant (Variation ID: 14364). For these reasons, this variant has been classified as Pathogenic. -

Not observed at significant frequency in large population cohorts (gnomAD); Published functional studies demonstrate a damaging effect as this variant results in almost absent enzymatic activity (Hyland et al., 1992); Nonsense variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss of function is a known mechanism of disease; This variant is associated with the following publications: (PMID: 3931636, 25525159, 8533783, 15666309, 1345174, 9152832, 20301635, 32382396) -
