Our verdict is Benign. Variant got -11 ACMG points: 2P and 13B. PP3PP1BS2BA1BP2

This summary comes from the ClinGen Evidence Repository: The NM_000527.5(LDLR):c.970G>A (p.Gly324Ser) variant is classified as Benign for Familial Hypercholesterolemia by applying evidence codes (BA1, BS2, BP2, PP1 and PP3) as defined by the ClinGen Familial Hypercholesterolemia Expert Panel LDLR-specific variant curation guidelines (https://doi.org/10.1101/2021.03.17.21252755). The supporting evidence is as follows: BA1 - FAF = 0.01153 (1.153%) in African/African American exomes (gnomAD v2.1.1). BS2 - Identified in 4 heterozygous non-affected family members from different labs.BP2 - variant identified 1 index case with heterozygous FH phenotype who is double heterozygous with NM_000384.3(APOB):c.10580G>A p.Arg3527Gln (ClinVar ID 17890) - classified as Pathogenic by the general ACMG guidelines (Chora et al., 2018).PP1 - variant segregates with phenotype in 2 informative meiosis in 1 family from Cardiovascular Research Group,Instituto Nacional de Saude Doutor Ricardo Jorge.PP3 - REVEL = 0.815.Variant has 1 stand alone, 1 Strong and 1 Supporting evidence codes towards Benign, enough to classify as Benign, and only 2 Supporting codes towards Pathogenic. The Benign criteria overwhelms the Pathogenic criteria, so we are confident in classifying this variant as Benign.

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]

Review Status: criteria provided, single submitter
Collection Method: clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -

Variant summary: LDLR c.970G>A (p.Gly324Ser) results in a non-conservative amino acid change located in the EGF-like domain (IPR000742) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.0012 in 282414 control chromosomes, predominantly at a frequency of 0.014 within the African or African-American subpopulation in the gnomAD database, including 2 homozygotes. The observed variant frequency within African or African-American control individuals in the gnomAD database is approximately 14 fold of the estimated maximal expected allele frequency for a pathogenic variant in LDLR causing Early Onset Coronary Artery Disease phenotype (0.001), strongly suggesting that the variant is a benign polymorphism found primarily in populations of African or African-American origin. Co-occurrences with other pathogenic LDLR variants have been reported (LDLR c.862G>A, p.E288K; LDLR c.1285G>A, p.Val429Met; internal data and Vaca_2011), providing supporting evidence for a benign role. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. 13 ClinVar submitters (evaluation after 2014) cite the variant as uncertain significance (n=2), likely pathogenic (n=1), pathogenic (n=1), likely benign (n=4) and benign (n=5). Based on the evidence outlined above, the variant was classified as benign. -

Significance: Likely benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

Variant identified in a genome or exome case(s) and assessed due to predicted null impact of the variant or pathogenic assertions in the literature or databases. Disclaimer: This variant has not undergone full assessment. The following are preliminary notes: This variant is present in ExAC with a MaxMAF of 1.3% in African chromosomes - disease prevalence is 1/200-1/300, occurs at greater freq than expected for disorder. It is classified in ClinVar with 1 star as both Likely pathogenic and Likely benign. It has been reported in 6 publications in HGMD but most suggest that it is not pathogenic. -

Significance: Benign

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
