Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 3P and 1B. PM1PP2BS1_Supporting

The NM_002335.4(LRP5):c.2392A>G(p.Thr798Ala) variant causes a missense change. The variant allele was found at a frequency of 0.0000143 in 1,613,732 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T798M) has been classified as Uncertain significance.

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 2 ACMG points.

PM1

In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 16 uncertain in NM_002335.4

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.

BS1

Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.0000394 (6/152328) while in subpopulation EAS AF = 0.00116 (6/5178). AF 95% confidence interval is 0.000505. There are 0 homozygotes in GnomAd4. There are 2 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
