This missense variant (also known as p.Cys188Tyr in the mature protein) replaces cysteine with tyrosine at codon 209 in the LDLR type A repeat 5 of the LDLR protein. This variant alters a conserved cysteine residue that is critical for proper protein folding and function (PMID: 2088165, 6091915, 15952897). Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in over 20 individuals affected with familial hypercholesterolemia (PMID: 11754108, 21310417, 22698793, 27824480, 28502495, 29396260). This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). Based on the available evidence, this variant is classified as Likely Pathogenic.
