This variant was found in 121/111864 control chromosomes, predominantly observed in the European (Finnish) subpopulation at a frequency of 0.001982 (9/4540) and European (Non-Finnish) subpopulation at a frequency of 0.001639 (92/56132). These frequencies are slightly higher than the estimated maximal expected allele frequency of a pathogenic LDLR variant (0.0012508), suggesting this is likely a benign polymorphism found primarily in the populations of European origin. This variant has been reported in many patients with familial hypercholesterolemia and myocardial infarction. However, multiple co-occurrences with a pathogenic LDLR variant and lack of co-segregation have been reported in these patients (Tejedor_2011, Komarova_2013, Klancar_2015, and Medeiros_2014). Two functional studies showed that LDLR p.Gly20Arg had comparable function to WT LDLR in total LDL signal, protein expression and localization and LDL particle binding (Thormaehlen_2015, Pavlouskova_2016). Although multiple clinical diagnostic laboratories classified this variant as uncertain significance, three clinical diagnostic laboratories classified thsi variant as benign/likely benign. Taken together, this variant is classified as likely benign.
GeneDx RCV000609054 SCV000730501 likely benign not specified 2017-04-05 criteria provided, single submitter clinical testing This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

Illumina Clinical Services Laboratory,Illumina RCV000211611 SCV001288138 uncertain significance Familial hypercholesterolemia 1 2018-08-16 criteria provided, single submitter 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. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
