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 replaces lysine with threonine at codon 316 of the PLOD1 protein (p.Lys316Thr). The lysine residue is moderately conserved and there is a moderate physicochemical difference between lysine and threonine. This variant is present in population databases (rs141881216, ExAC 0.03%). This variant has not been reported in the literature in individuals affected with PLOD1-related conditions. ClinVar contains an entry for this variant (Variation ID: 579966). 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. -
