Labcorp Genetics (formerly Invitae), Labcorp RCV001208294 SCV001379674 pathogenic Familial hypercholesterolemia 2022-10-20 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). This sequence change replaces aspartic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 224 of the LDLR protein (p.Asp224Gly). This missense change has been observed in individuals with hypercholesterolemia (PMID: 1301956, 17539906, 23375686; Invitae). It has also been observed to segregate with disease in related individuals. This variant is also known as p.D203G. ClinVar contains an entry for this variant (Variation ID: 251374). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt LDLR protein function. This variant disrupts the p.Asp224 amino acid residue in LDLR. Other variant(s) that disrupt this residue have been observed in individuals with LDLR-related conditions (PMID: 7649546, 16627557), which suggests that this may be a clinically significant amino acid residue. For these reasons, this variant has been classified as Pathogenic.
