IV. Impact on Lipid Metabolism and Cholesterol Levels
Lecithin Cholesterol Acyltransferase Deficiency significantly impacts lipid metabolism and cholesterol levels, leading to dysregulation of crucial processes in the body. The absence or reduced activity of the LCAT enzyme results in impaired esterification of cholesterol, affecting the formation and functionality of high-density lipoprotein (HDL) particles;
HDL cholesterol, commonly known as ″good cholesterol,″ plays a vital role in the reverse transport of cholesterol from peripheral tissues back to the liver for processing and excretion; In LCAT Deficiency, the dysfunctional HDL particles are unable to perform this function effectively, contributing to decreased levels of circulating HDL cholesterol.
Moreover, the deficiency of LCAT leads to the accumulation of unesterified cholesterol in plasma, which can contribute to the formation of atherosclerotic plaques in blood vessels. As a result, individuals with LCAT Deficiency are at an increased risk of developing cardiovascular diseases such as atherosclerosis, coronary artery disease, and other related complications.
The dysregulation of lipid metabolism in LCAT Deficiency can also impact other lipid parameters, including low-density lipoprotein (LDL) cholesterol levels and triglycerides. Monitoring these lipid components is essential in assessing the overall cardiovascular risk profile of individuals with the disorder.
