Variant summary

Our verdict is Likely pathogenic. The variant received 7 ACMG points: 7P and 0B. PM5PP2PP3_Strong

The ENST00000294304.12(LRP5):​c.1265C>T​(p.Ala422Val) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000991 in 1,613,718 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 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. A422T) has been classified as Likely 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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 7 ACMG points.

PM5
Other missense variant is known to change same aminoacid residue: Variant chr11-68386564-G-A is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 3600191.Status of the report is criteria_provided_single_submitter, 1 stars.
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.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.989
