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

Our verdict: Benign. The variant received -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.51).
• BP6: Variant 9-2621559-G-A is Benign according to our data. Variant chr9-2621559-G-A is described in ClinVar as Likely_benign. ClinVar VariationId is 1215620.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.00516 (1250/242418) while in subpopulation EAS AF = 0.0338 (749/22174). AF 95% confidence interval is 0.0318. There are 19 homozygotes in GnomAdExome4. There are 589 alleles in the male GnomAdExome4 subpopulation. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 3 gene
