Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 5P and 1B. PM5 PM2 PP4 BP4

This summary comes from the ClinGen Evidence Repository: The NM_000527.5(LDLR):c.1414G>A (p.Asp472Asn) variant is classified as Uncertain significance - insufficient evidence for Familial Hypercholesterolemia by applying ACMG/AMP evidence codes PM2, PM5, PP4 and BP4 as defined by the ClinGen Familial Hypercholesterolemia Expert Panel LDLR-specific variant curation guidelines (specification version 1.2) on 31 January 2025. The supporting evidence is as follows: PM2 - PopMax MAF = 0.0001120 (0.0112%) in Remaining exomes+genomes (gnomAD v4.1.0); PM5 - 1 other missense variant in the same codon: - NM_000527.5(LDLR):c.1414G>T (p.Asp472Tyr) (ClinVar ID 183116) -Pathogenic by these guidelines. There is 1 variant in the same codon classified as Pathogenic by these guidelines; BP4 - REVEL = 0.318, it is below 0.50, splicing evaluation required. Functional data on splicing not available. A) not on limits. B) does not create AG. Variant is not predicted to alter splicing; PP4 - Variant meets PM2. Identified in at least 1 index case fulfilling Japanese Atherosclerosis Society criteria for FH from PMID 36229376, after alternative causes of high cholesterol were excluded.

Genes affected

LDLR (HGNC:6547): (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. The encoded protein is normally bound at the cell membrane, where it binds low density lipoprotein/cholesterol and is taken into the cell. Lysosomes release the cholesterol, which is made available for repression of microsomal enzyme 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase, the rate-limiting step in cholesterol synthesis. At the same time, a reciprocal stimulation of cholesterol ester synthesis takes place. Mutations in this gene cause the autosomal dominant disorder, familial hypercholesterolemia. Alternate splicing results in multiple transcript variants.[provided by RefSeq, May 2022]

MIR6886 (HGNC:50121): (microRNA 6886) microRNAs (miRNAs) are short (20-24 nt) non-coding RNAs that are involved in post-transcriptional regulation of gene expression in multicellular organisms by affecting both the stability and translation of mRNAs. miRNAs are transcribed by RNA polymerase II as part of capped and polyadenylated primary transcripts (pri-miRNAs) that can be either protein-coding or non-coding. The primary transcript is cleaved by the Drosha ribonuclease III enzyme to produce an approximately 70-nt stem-loop precursor miRNA (pre-miRNA), which is further cleaved by the cytoplasmic Dicer ribonuclease to generate the mature miRNA and antisense miRNA star (miRNA*) products. The mature miRNA is incorporated into a RNA-induced silencing complex (RISC), which recognizes target mRNAs through imperfect base pairing with the miRNA and most commonly results in translational inhibition or destabilization of the target mRNA. The RefSeq represents the predicted microRNA stem-loop. [provided by RefSeq, Sep 2009]
