This variant has also been id entified in 15/126710 European chromosomes by the Genome Aggregation Database (g nomAD, http://gnomad.broadinstitute.org; dbSNP rs137929307). However, this frequ ency is low enough to be consistent with the frequency of FH in the general popu lation. Furthermore, in vitro functional studies provide some evidence that the p.Gly592Glu variant may impact protein function (Romano 2011). In summary, this variant meets criteria to be classified as pathogenic for familial hypercholeste rolemia in an autosomal dominant manner based upon presence in multiple affected individuals and segregation studies.

Invitae	RCV000587007	SCV000544669	pathogenic	Familial hypercholesterolemia	2020-01-04	criteria provided, single submitter	clinical testing	This sequence change replaces glycine with glutamic acid at codon 592 of the LDLR protein (p.Gly592Glu). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and glutamic acid. This variant is present in population databases (rs137929307, ExAC 0.009%). This variant is clearly defined as a familial hypercholesterolemia causative allele (PMID: 15864114,20663204, 21310417), and is a common cause of familial hypercholesterolemia in individuals of European ancestry (PMID: 26238499, 23375686, 21925044), This variant is also known as p.Gly571Glu in the literature. ClinVar contains an entry for this variant (Variation ID: 161271). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies. For these reasons, this variant has been classified as Pathogenic.
GeneDx	RCV000162001	SCV000582282	pathogenic	not provided	2018-05-04	criteria provided, single submitter	clinical testing	The G592E variant in the LDLR gene, previously reported as G571E due to alternate nomenclature, has been reported many times in association with heterozygous FH and homozygous FH (Hobbs et al., 1992; Chmara et al., 2010; Goldman et al., 2010; Bertolini et al., 2013; Mollaki et al., 2014; Braenne et al., 2016; Gabcova et al., 2017). The G592E variant is observed in 15/126,710 (0.01%) alleles from individuals of non-Finnish European background in large population cohorts (Lek et al., 2016). The G592E variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. Functional studies demonstrate that this variant would lead to deficient LDLR protein (Susan-Resiga et al., 2017).

Integrated Genetics/Laboratory Corporation of America	RCV000587007	SCV000697209	pathogenic	Familial hypercholesterolemia	2016-09-13	criteria provided, single submitter	clinical testing	Variant summary: The LDLR c.1775G>A (p.Gly592Glu) variant involves the alteration of a conserved nucleotide. Gly592 is highly conserved across species, and 5/5 in silico tools predict a damaging outcome for this variant. This variant was found in 6/121608 control chromosomes at a frequency of 0.0000493, which does not exceed the estimated maximal expected allele frequency of a pathogenic LDLR variant (0.0025031). This variant has been reported in many FH patients in both heterozygous, compound heterozygous, and homozygous states with evidence of co-segregation in some of the families. Functional studies indicate that the variant of interest has defective LDL receptor activity. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as pathogenic/likely pathogenic. Taken together, this variant is classified as pathogenic.

Walther, Weindel und Kollegen	RCV000172964	SCV000987017	pathogenic	Familial hypercholesterolemia 1	2018-10-29	criteria provided, single submitter	clinical testing	This nucleotide substitution causes an exchange of the amino acid of glycine (Gly) to glutamic acid (Glu) p.Gly592Glu (legacy name: p.Gly571Glu). This change has already been described in the literature as FH Sicily, FH Foggia 1 and FH Naples 4 and has been found in patients with familial hypercholesterolemia and is associated with elevated cholesterol and LDL-C levels. It results in a reduced amount of biologically active LDL receptors on the cell surface. We observed this variant in a patient with TC up to 350 mg/dl and LDL-C approx 290 mg/dl at the age of 48 and in a patient with TC up to 300 mg/dl and LDL-C approx 250 mg/dl at the age of 5.
