Genes affected

LRP4 (HGNC:6696): (LDL receptor related protein 4) This gene encodes a member of the low-density lipoprotein receptor-related protein family. The encoded protein may be a regulator of Wnt signaling. Mutations in this gene are associated with Cenani-Lenz syndrome. [provided by RefSeq, May 2010]

LRP4-AS1 (HGNC:44128): (LRP4 antisense RNA 1)

ACMG classification

Verdict is Benign. Variant got -21 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.47).
• BP6: Variant 11-46868056-C-T is Benign according to our data. Variant chr11-46868056-C-T is described in ClinVar as [Benign]. Clinvar id is 467791.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr11-46868056-C-T is described in Lovd as [Benign].
• BP7: Synonymous conserved (PhyloP=0.25 with no splicing effect.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00929 (1415/152234) while in subpopulation NFE AF= 0.014 (955/68018). AF 95% confidence interval is 0.0133. There are 13 homozygotes in gnomad4. There are 675 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases was too high to be consistent with this variant causing disease. Therefore, this variant is classified as benign. -
