WebOne of the most distinctive features regarding lipoprotein (a) [Lp (a)] has been the variability in levels between different population groups. Although substantial knowledge has been obtained regarding genetic variability of apo (a) between different populations, the underlying causes for this difference in levels are still largely unresolved. WebRecent studies have clarified the role of lipoprotein(a) [Lp(a)], relative to other lipoproteins, in atherogenesis. 1 This JAMA Insights article discusses several clinical aspects of Lp(a), including the association with cardiovascular disease risk, considerations regarding measurement, guideline recommendations, and emerging therapies. Lp(a) is a low-density …
WebLp (a) levels are inversely correlated with the genetically determined apo (a) isoform size, with higher levels of plasma Lp (a) being associated with smaller apo (a) isoform sizes as represented by fewer kringle IV repeats. Lp (a) levels can also vary considerably among individuals with a given apo (a) isoform size ( 4. ). WebApr 7, 2024 · Lipoproteins are protein molecules that transport fat in the body.
