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

Verdict is Benign. Variant got -10 ACMG points.

• BP6: Variant 9-2622146-ACGGCGG-A is Benign according to our data. Variant chr9-2622146-ACGGCGG-A is described in ClinVar as [Likely_benign]. Clinvar id is 420696.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.00159 (240/150670) while in subpopulation SAS AF= 0.0044 (21/4774). AF 95% confidence interval is 0.00326. There are 1 homozygotes in gnomad4. There are 107 alleles in male gnomad4 subpopulation. Median coverage is 0. This position pass quality control queck.
• BS2: High Homozygotes in GnomAdExome4 at 6 AR gene
