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.

The PLOD1 c.785C>T; p.Thr262Ile variant (rs147940796), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 459828). This variant is found in the African population with an overall allele frequency of 0.15% (37/24018 alleles) in the Genome Aggregation Database. The threonine at codon 262 is highly conserved, and computational analyses (SIFT, PolyPhen-2) predict that this variant is deleterious. However, due to limited information, the clinical significance of the p.Thr262Ile variant is uncertain at this time. -

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

The p.T262I variant (also known as c.785C>T), located in coding exon 8 of the PLOD1 gene, results from a C to T substitution at nucleotide position 785. The threonine at codon 262 is replaced by isoleucine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
