Variant summary

Our verdict is Likely pathogenic. The variant received 11 ACMG points: 11P and 0B. PM1PM3PP1_ModeratePM2PP3PP4PS4_Supporting

This summary comes from the ClinGen Evidence Repository: The NM_000527.5(LDLR):c.1090T>C (p.Cys364Arg) variant is classified as Likely Pathogenic for Familial Hypercholesterolemia by applying ACMG/AMP evidence codes PM1, PM2, PM3, PP1_Moderate, PP3, PP4 and PS4_Supporting as defined by the ClinGen Familial Hypercholesterolemia Expert Panel LDLR-specific variant curation guidelines (specification version 1.2) on 24 March 2025. The supporting evidence is as follows: PM1: Variant meets PM2 and alters Cys364, one of the highly conserved cysteine residues listed. PM2: PopMax MAF=0.00001666 (0.001666%) in Admixed American exomes + genomes (gnomAD v4.1.0). PP3: REVEL=0.984. PS4_Supporting, PP4: Variant meets PM2 and is identified in 2 unrelated index cases (1 case with DLCN score >=6 from Research Lab of Molecular Genetics of Lipid Metabolism, Italy; 1 case with modified Simon-Broome criteria from PMID 23064986 (Ahmad et al., 2012), USA). PP1_Moderate: Variant segregates with FH phenotype in 5 informative meiosis from 2 families from different labs (Laboratory of Genetics and Molecular Cardiology, Brazil and Research Lab of Molecular Genetics of Lipid Metabolism, Italy): 3 affected family members have the variant and 2 unaffected family members do not have the variant.PM3: Variant meets PM2 and is identified in at least 1 clinically diagnosed HoFH, homozygous for the variant (PMID 37119068; PMID 27940769).

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]
