Description

Variant of Uncertain Significance due to insufficient evidence: This missense variant (also known as p.Gly495Ser in the mature protein) is located in LDLR type B repeat 3 of EGF precursor homology domain of the LDLR protein. Computational prediction tools and conservation analyses are inconclusive regarding the impact of this variant on the protein function. Computational splicing tools suggest that this variant may not impact RNA splicing. To our knowledge, functional assays have not been performed for this variant. This variant has been reported in a few individuals affected with familial hypercholesterolemia (PMID: 20809525, 22883975, 29399563). This variant has also been identified in 24/277174 chromosomes (14/24954 African chromosomes) in the general population by the Genome Aggregation Database (gnomAD). Available evidence is insufficient to determine the pathogenicity of this variant conclusively.
