Description:
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).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zanoni, Paolo -- Khetarpal, Sumeet A -- Larach, Daniel B -- Hancock-Cerutti, William F -- Millar, John S -- Cuchel, Marina -- DerOhannessian, Stephanie -- Kontush, Anatol -- Surendran, Praveen -- Saleheen, Danish -- Trompet, Stella -- Jukema, J Wouter -- De Craen, Anton -- Deloukas, Panos -- Sattar, Naveed -- Ford, Ian -- Packard, Chris -- Majumder, Abdullah al Shafi -- Alam, Dewan S -- Di Angelantonio, Emanuele -- Abecasis, Goncalo -- Chowdhury, Rajiv -- Erdmann, Jeanette -- Nordestgaard, Borge G -- Nielsen, Sune F -- Tybjaerg-Hansen, Anne -- Schmidt, Ruth Frikke -- Kuulasmaa, Kari -- Liu, Dajiang J -- Perola, Markus -- Blankenberg, Stefan -- Salomaa, Veikko -- Mannisto, Satu -- Amouyel, Philippe -- Arveiler, Dominique -- Ferrieres, Jean -- Muller-Nurasyid, Martina -- Ferrario, Marco -- Kee, Frank -- Willer, Cristen J -- Samani, Nilesh -- Schunkert, Heribert -- Butterworth, Adam S -- Howson, Joanna M M -- Peloso, Gina M -- Stitziel, Nathan O -- Danesh, John -- Kathiresan, Sekar -- Rader, Daniel J -- CHD Exome+ Consortium -- CARDIoGRAM Exome Consortium -- Global Lipids Genetics Consortium -- R01 DK089256/DK/NIDDK NIH HHS/ -- R01 HL117078/HL/NHLBI NIH HHS/ -- TL1 RR024133/RR/NCRR NIH HHS/ -- TL1R000138/PHS HHS/ -- TL1RR024133/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2016 Mar 11;351(6278):1166-71. doi: 10.1126/science.aad3517.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departments of Genetics and Medicine, Division of Translational Medicine and Human Genetics, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA 19104, USA. ; Departments of Genetics and Medicine, Division of Translational Medicine and Human Genetics, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA 19104, USA.
