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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -11 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.44).

BP6

Variant 11-46896203-C-A is Benign according to our data. Variant chr11-46896203-C-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 288216.

BS1

Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.00208 (317/152380) while in subpopulation AMR AF = 0.00385 (59/15314). AF 95% confidence interval is 0.00307. There are 3 homozygotes in GnomAd4. There are 154 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 3 AR,SD gene
