Genes affected

VLDLR (HGNC:12698): (very low density lipoprotein receptor) The low density lipoprotein receptor (LDLR) gene family consists of cell surface proteins involved in receptor-mediated endocytosis of specific ligands. This gene encodes a lipoprotein receptor that is a member of the LDLR family and plays important roles in VLDL-triglyceride metabolism and the reelin signaling pathway. Mutations in this gene cause VLDLR-associated cerebellar hypoplasia. Alternative splicing generates multiple transcript variants encoding distinct isoforms for this gene.

VLDLR-AS1 (HGNC:49621): (VLDLR antisense RNA 1)

ACMG classification

Our verdict: Benign. The variant received -13 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.7).
• BP6: Variant 9-2622077-C-G is Benign according to our data. Variant chr9-2622077-C-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 366350.
• BS1: Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0114 (1728/151894) while in subpopulation NFE AF = 0.0179 (1216/67874). AF 95% confidence interval is 0.0171. There are 13 homozygotes in GnomAd4. There are 795 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 13 AR gene
