This variant occurs in a non-coding region of the LDLR gene. It does not change the encoded amino acid sequence of the LDLR protein. This variant is not present in population databases (gnomAD no frequency). This variant has been observed in individual(s) with familial hypercholesterolemia (PMID: 9610768). This variant is also known as -92 (FH-Pedi-2). ClinVar contains an entry for this variant (Variation ID: 438314). Studies have shown that this variant alters LDLR gene expression (PMID: 9610768). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
