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 variant is also reported in ClinVar (Variation ID: 183255), and is found in the general population with an overall allele frequency of 0.24% (692/282864 alleles) in the Genome Aggregation Database. Computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.683). In vitro functional analyses demonstrate reduced Wnt signaling, but no effect on expression of downstream genes (Cnossen 2016, Korvala 2012). Due to conflicting information, the clinical significance of this variant is uncertain at this time. References: Caetano da Silva C et al.
