This variant was found in 34/121530 control chromosomes, predominantly observed in the African subpopulation at a frequency of 0.0031712 (33/10406). This frequency is about 3 times the estimated maximal expected allele frequency of a pathogenic LDLR variant (0.0010005), suggesting this is possibly a benign polymorphism found primarily in the populations of African origin. This variant has been reported in multiple affected individuals (mostly with African ethnicities) without strong evidence for causality. In addition, one clinical diagnostic laboratory/database classified this variant as likely benign and another one classified it as VUS, all without evidence for independent evaluation. In vivo study of LDL metabolism showed this variant with a reduced in vivo activity of LDL-R (80% of WT; Arca_1997 and Arca_1994). Taken together, this variant is classified as VUS.
