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]

The LRP5 c.1828G>T variant is predicted to result in the amino acid substitution p.Gly610Trp. This variant was reported in the homozygous state in two related siblings with hearing loss (Xia et al. 2017. PubMed ID: 28677207). A variant impacting the same amino acid position (c.1828G>A, p.Gly610Arg) has been reported in trans with a second variant in LRP5 in an individual with familial exudative vitreoretinopathy and reduced bone density (Qin et al. 2005. PubMed ID: 15981244); the heterozygous parent was unaffected. This variant is reported in 0.022% of alleles in individuals of East Asian descent in gnomAD. This variant is interpreted as likely pathogenic. -
