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 was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.1477254).

BS1

Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.0000575 (77/1339884) while in subpopulation SAS AF = 0.000799 (59/73822). AF 95% confidence interval is 0.000635. There are 1 homozygotes in GnomAdExome4. There are 52 alleles in the male GnomAdExome4 subpopulation. Median coverage is 34. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The c.64A>T (p.S22C) alteration is located in exon 1 (coding exon 1) of the VLDLR gene. This alteration results from a A to T substitution at nucleotide position 64, causing the serine (S) at amino acid position 22 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
