Variant summary

Our verdict is Pathogenic. The variant received 12 ACMG points: 12P and 0B. PS4PP1_StrongPM2PP3PP4

This summary comes from the ClinGen Evidence Repository: The NM_000527.5(LDLR):c.1444G>A (p.Asp482Asn) variant is classified as Pathogenic for Familial Hypercholesterolemia by applying ACMG/AMP evidence codes PS4, PP1_Strong, PM2, PP3 and PP4 as defined by the ClinGen Familial Hypercholesterolemia Expert Panel LDLR-specific variant curation guidelines (specification version 1.2) on 23 June 2023. The supporting evidence is as follows: PM2: PopMax MAF = 0.00009 (0.009%) in European (Non-Finnish) exomes+genomes (gnomAD v2.1.1). PP3: REVEL=0.945. PS4, PP4: Variant meets PM2 and is identified in at least 14 unrelated index cases who fulfill criteria for FH (3 cases with Simon-Broome criteria from Molecular Genetics Laboratory, Centre for Cardiovascular Surgery and Transplantation, Czech Republic; 3 cases with DLCN score >=6 and 1 case with Simon-Broome criteria from Service de Biochimie et de Biologie Moléculaire, Hospices Civils de Lyon, Lyon, France; 3 cases with DLCN score >=6 from Robarts Research Institute, Canada; 3 cases with DLCN score >=6 from Cardiovascular Genetics Laboratory, PathWest Laboratory Medicine WA, Australia; 1 case with DLCN score>=6 from Color Health, Inc, USA). PP1_Strong: Variant segregates with FH phenotype in at least 11 informative meioses in 4 families from different labs (Molecular Genetics Laboratory, Centre for Cardiovascular Surgery and Transplantation, Czech Republic and Service de Biochimie et de Biologie Moléculaire, Hospices Civils de Lyon, Lyon, France): 8 affected family members have the variant and 3 unaffected family members do not have the variant.

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]
