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]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in the LRP5 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 71 curated pathogenic missense variants (we use a threshold of 10). The gene has 23 curated benign missense variants. Gene score misZ: 1.6684 (below the threshold of 3.09). Trascript score misZ: 3.6986 (above the threshold of 3.09). GenCC associations: The gene is linked to exudative vitreoretinopathy 4, autosomal dominant osteopetrosis 1, osteoporosis-pseudoglioma syndrome, autosomal dominant osteosclerosis, Worth type, polycystic liver disease 4 with or without kidney cysts, bone mineral density quantitative trait locus 1, osteosclerosis-developmental delay-craniosynostosis syndrome, hyperostosis corticalis generalisata, exudative vitreoretinopathy, polycystic liver disease 1, inherited retinal dystrophy.

BP4

Computational evidence support a benign effect (MetaRNN=0.16687435).
