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

Verdict is Benign. Variant got -9 ACMG points.

• BP6: Variant 11-68312693-GC-G is Benign according to our data. Variant chr11-68312693-GC-G is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 287479.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=3, Uncertain_significance=1}.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00667 (966/144788) while in subpopulation NFE AF= 0.0108 (703/65190). AF 95% confidence interval is 0.0101. There are 5 homozygotes in gnomad4. There are 417 alleles in male gnomad4 subpopulation. Median coverage is 30. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 5 SD gene
