This sequence change replaces tryptophan, which is neutral and slightly polar, with glycine, which is neutral and non-polar, at codon 207 of the MMP13 protein (p.Trp207Gly). This variant is present in population databases (rs140059558, gnomAD 0.01%). This missense change has been observed in individuals with autosomal recessive metaphyseal dysplasia, Spahr type (PMID: 24648384, 27576021; internal data). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 183687). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt MMP13 protein function with a positive predictive value of 80%. For these reasons, this variant has been classified as Pathogenic. -
