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

Our verdict: Benign. The variant received -8 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.79).
• BS1: Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.000861 (131/152102) while in subpopulation EAS AF = 0.021 (109/5180). AF 95% confidence interval is 0.0178. There are 1 homozygotes in GnomAd4. There are 78 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
