Variant summary

Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PM1PM2PM5PP2PP3_StrongPP5

The NM_002335.4(LRP5):c.731C>T(p.Thr244Met) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000434 in 1,613,006 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 13/21 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T244R) 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 made for transcript

Verdict is Pathogenic. Variant got 12 ACMG points.

PM1

In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 5 uncertain in NM_002335.4

PM2

Very rare variant in population databases, with high coverage;

PM5

Other missense variant is known to change same aminoacid residue: Variant chr11-68363791-C-G is described in Lovd as [Likely_pathogenic].

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), LRP5. . Gene score misZ 1.6684 (greater than the threshold 3.09). Trascript score misZ 3.6986 (greater than threshold 3.09). GenCC has associacion of gene with exudative vitreoretinopathy 4, polycystic liver disease 4 with or without kidney cysts, polycystic liver disease 1, exudative vitreoretinopathy, osteosclerosis-developmental delay-craniosynostosis syndrome, bone mineral density quantitative trait locus 1, autosomal dominant osteopetrosis 1, hyperostosis corticalis generalisata, osteoporosis-pseudoglioma syndrome, autosomal dominant osteosclerosis, Worth type, inherited retinal dystrophy.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.979

PP5

Variant 11-68363791-C-T is Pathogenic according to our data. Variant chr11-68363791-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 40289.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr11-68363791-C-T is described in Lovd as [Pathogenic].
