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.

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.09435633).

BS1

Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.000382 (559/1461872) while in subpopulation SAS AF= 0.000696 (60/86238). AF 95% confidence interval is 0.000554. There are 0 homozygotes in gnomad4_exome. There are 277 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The c.836G>A (p.R279Q) alteration is located in exon 6 (coding exon 6) of the VLDLR gene. This alteration results from a G to A substitution at nucleotide position 836, causing the arginine (R) at amino acid position 279 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
