Rare variant in scavenger receptor BI raises HDL cholesterol and increases risk of coronary heart disease. Science. doi: 10.1126/science.aad3517.

Interpretive Summary: Scavenger receptor BI is the major receptor for high-density lipoprotein cholesterol. In humans, high amounts of high-density lipoprotein cholesterol in plasma are associated with a lower risk of coronary heart disease. When mice are depleted of the Scarb1 gene that encodes scavenger receptor BI, they have markedly elevated high-density lipoprotein cholesterol levels but, paradoxically, increased atherosclerosis. The impact of scavenger receptor BI on high density lipoprotein metabolism and coronary heart disease risk in humans remains unclear. Through targeted sequencing of coding regions of lipid-modifying genes in 328 individuals with extremely high plasma high density lipoprotein cholesterol levels, we identified one individual who had identical pairs of a genetic variant in the SCARB1 gene that resulted in loss of function of the receptor. This variant impairs processing of scavenger receptor BI and abolishes high density lipoprotein cholesterol uptake in several cell and animal models. Large population-based studies revealed that individuals who are carriers of this genetic variant have significantly increased levels of plasma high density lipoprotein cholesterol. Against the traditional dogma, these carriers of this genetic variant have elevated high density lipoprotein and an increased risk of coronary heart disease.

Technical Abstract: Scavenger receptor BI (SR-BI) is the major receptor for high-density lipoprotein (HDL) cholesterol (HDL-C). In humans, high amounts of HDL-C in plasma are associated with a lower risk of coronary heart disease (CHD). Mice that have depleted Scarb1 (SR-BI knockout mice) have markedly elevated HDL-C levels but, paradoxically, increased atherosclerosis. The impact of SR-BI on HDL metabolism and CHD risk in humans remains unclear. Through targeted sequencing of coding regions of lipid-modifying genes in 328 individuals with extremely high plasma HDL-C levels, we identified a homozygote for a loss-of-function variant, in which leucine replaces proline 376 (P376L), in SCARB1, the gene encoding SR-BI. The P376L variant impairs posttranslational processing of SR-BI and abrogates selective HDL cholesterol uptake in transfected cells, in hepatocyte-like cells derived from induced pluripotent stem cells from the homozygous subject, and in mice. Large population-based studies revealed that subjects who are heterozygous carriers of the P376L variant have significantly increased levels of plasma HDL-C. P376L carriers have a profound HDL-related phenotype and an increased risk of CHD (odds ratio = 1.79, which is statistically significant).
