Molecular Genetics, Royal Melbourne Hospital RCV003994664 SCV004812501 uncertain significance Hypercholesterolemia, familial, 1 2023-03-30 criteria provided, single submitter clinical testing This sequence change in LDLR is predicted to replace glycine with valine at codon 324, p.(Gly324Val). The glycine residue is highly conserved (100 vertebrates, UCSC), and is located in the EGF-like 1 domain. There is a large physicochemical difference between glycine and valine. This variant is absent from the population database gnomAD v2.1 and v3.1. To our knowledge, this variant has not been reported in the relevant literature. At least one patient with this variant displayed a clinical diagnosis of familial hypercholesterolaemia (FH) with a Dutch Lipid Clinic Network score of 6, which is highly specific for FH (Royal Melbourne Hospital). Multiple lines of computational evidence predict a deleterious effect for the missense substitution (6/6 algorithms). Based on the classification scheme RMH Modified ACMG Guidelines v1.5.1, this variant is classified as a VARIANT OF UNCERTAIN SIGNIFICANCE. Following criteria are met: PM2_Supporting, PP3, PP4.
