This variant was found in 41/94810 control chromosomes, predominantly observed in the African subpopulation at a frequency of 0.004103 (31/7556). This frequency is about 205 times the estimated maximal expected allele frequency of a pathogenic PCSK9 variant (0.00002), suggesting this is likely a benign polymorphism found primarily in the populations of African origin. The variant has been reported in the literature as a SNP and has been observed at equal frequencies both in patients with low LDL-C and high LDL-C. Therefore, its role in the pathophysiology of Familial Hypercholesterolemia and early onset CAD is suspect. One clinical diagnostic laboratory classified this variant as uncertain significance. Taken together, due to the relatively high frequency of the variant in the control population, this variant has been classified as benign.
