Genes affected

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

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.

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.53).
• BP6: Variant 9-2621564-G-A is Benign according to our data. Variant chr9-2621564-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 673304.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS2: High Homozygotes in GnomAd4 at 20 gene
