Description
The p.Arg574Cys variant in LDLR has been reported in 14 individuals with familial hypercholesterolemia (PMID: 29290422, 25647241, 22698793, 20145306, 25487149, 23375686, 11462246, 26892515, 19446849), and has been identified in 0.006% (8/129194) European non-Finnish chromosomes. 0.004% (1/25116) European Finnish chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs185098634). Please note that for diseases with clinical variability, or reduced penetrance, pathogenic variants may be present at a low frequency in the general population. This variant has also been reported in ClinVar as a VUS, likely pathogenic, and pathogenic(Variation ID#: 183123). Computational prediction tools and conservation analyses suggest that this variant may impact the protein, though this information is not predictive enough to determine pathogenicity. In summary, while there is some suspicion for a pathogenic role, the clinical significance of this variant is uncertain. ACMG/AMP Criteria applied: PS4_moderate, PM2_supporting, PP3 (Richards 2015).

Description
This missense variant replaces arginine with cysteine at codon 574 of the LDLR protein. This variant is also known as p.Arg553Cys in the mature protein. This variant alters a conserved arginine residue in the LDLR type B repeat 5 of the LDLR protein (a.a. 572-615), where pathogenic missense variants are found enriched (ClinVar-LDLR). Computational prediction suggests that this variant may have a deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). A high-throughput experimental study has shown that this variant may not disrupt LDLR function (PMID: 25647241). This variant has been reported in over 10 individuals affected with familial hypercholesterolemia (PMID: 11462246, 15823288, 19318025, 19446849, 26892515, 27050191, 30293936, 34297352). This variant has been stated to segregate with disease in a German family, although detailed data from the family study has not been provided (PMID: 11462246). This variant has been identified in 10/282878 chromosomes in the general population by the Genome Aggregation Database (gnomAD). A different variant affecting the same codon, p.Arg574His, is considered to be disease-causing (ClinVar variation ID: 251996), suggesting that arginine at this position is important for LDLR protein function. Based on the available evidence, this variant is classified as Likely Pathogenic.
