Variant summary

Our verdict is Pathogenic. Variant got 15 ACMG points: 15P and 0B. PS1PM1PM2PM5PP2PP3_Strong

The NM_002335.4(LRP5):c.1828G>A(p.Gly610Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000018 in 1,613,960 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 12/21 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Another nucleotide change resulting in same amino acid change has been previously reported as Pathogenicin Lovd. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G610W) has been classified as Pathogenic.

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]

Pathogenic, criteria provided, single submitter	clinical testing	Invitae	Jul 17, 2023	This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 610 of the LRP5 protein (p.Gly610Arg). This variant is present in population databases (rs80358313, gnomAD 0.003%). This missense change has been observed in individual(s) with autosomal dominant osteoporosis with retinopathy and autosomal recessive osteoporosis-pseudoglioma syndrome (PMID: 15981244, 16252235, 20340138). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 6294). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt LRP5 protein function. Experimental studies have shown that this missense change affects LRP5 function (PMID: 16252235). For these reasons, this variant has been classified as Pathogenic. -
