Comment:

The LDLR c.264G>A (p.(Arg88=) synonymous variant has not been reported in individuals with LDLR-related conditions in the published literature. It also has not been reported in large, multi-ethnic general populations (Genome Aggregation Database, http://gnomad.broadinstitute.org). Analysis of this variant using software algorithms for the prediction of the effect of nucleotide changes on splicing yielded predictions that this variant does not affect LDLR mRNA splicing. Based on the available information, we are unable to determine the clinical significance of this variant.
