Genes affected
LRP5 (HGNC:6697): (LDL receptor related protein 5) This gene encodes a transmembrane low-density lipoprotein receptor that binds and internalizes ligands in the process of receptor-mediated endocytosis. This protein also acts as a co-receptor with Frizzled protein family members for transducing signals by Wnt proteins and was originally cloned on the basis of its association with type 1 diabetes mellitus in humans. This protein plays a key role in skeletal homeostasis and many bone density related diseases are caused by mutations in this gene. Mutations in this gene also cause familial exudative vitreoretinopathy. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2014]

This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 454 of the LRP5 protein (p.Val454Met). This variant is present in population databases (rs373910016, gnomAD 0.0009%). This missense change has been observed in individual(s) with polycystic liver disease (PMID: 24706814). ClinVar contains an entry for this variant (Variation ID: 183258). 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) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on LRP5 protein function. 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. -
