Article Synopsis
  • PCSK9 is crucial for regulating LDL-cholesterol and certain variants, like p.Ser127Arg, lead to higher cholesterol levels and are mainly found in France, with few in South Africa and Norway due to a common ancestor effect.
  • The study analyzed 14 p.Ser127Arg carriers from eight families and compared them with other variants to understand their genetic background and health impact.
  • Results indicated that the common ancestor lived about 775 years ago, and carriers of p.Ser127Arg had significantly higher LDL-C levels, suggesting it may have a stronger effect on cholesterol levels compared to other mutations.

High blood levels of low-density lipoprotein (LDL)-cholesterol (LDL-C) are associated with atherosclerosis, mainly by promoting foam cell accumulation in vessels. As cholesterol is an essential component of cell plasma membranes and a regulator of several signaling pathways, LDL-C excess may have wider cardiovascular toxicity. We examined, in untreated hypercholesterolemia (HC) patients, selected regardless of the cause of LDL-C accumulation, and in healthy participants (HP), the expression of the adenosine A receptor (AR), an anti-inflammatory and vasodilatory protein with cholesterol-dependent modulation, and Flotillin-1, protein marker of cholesterol-enriched plasma membrane domains.
