Description

Variant of Uncertain Significance due to insufficient evidence: This variant causes a single nucleotide change in the promoter region of the LDLR gene. To our knowledge, functional assays have not been performed for this variant nor has this variant been reported in individuals affected with familial hypercholesterolemia in the literature. This variant is rare in the general population and has been identified in 0/277264 chromosomes by the Genome Aggregation Database (gnomAD). Available evidence is insufficient to determine the pathogenicity of this variant conclusively.

Description

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. 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 not been reported in the literature in individuals affected with LDLR-related conditions. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown.
