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 -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.67).
• BP6: Variant 9-2621675-G-A is Benign according to our data. Variant chr9-2621675-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 1201678.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0106 (1614/151932) while in subpopulation NFE AF= 0.0167 (1134/67892). AF 95% confidence interval is 0.0159. There are 12 homozygotes in gnomad4. There are 741 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 12 gene
