The enzyme is bound to [[high-density lipoprotein]]s (HDLs) (alpha-LCAT) and LDLs (beta-LCAT) in the [[blood plasma]].&lt;ref&gt;{{Cite journal|date=2016-08-08|title=Lecithin-Cholesterol Acyltransferase Deficiency: Overview, Presentation, Differential Diagnosis|url=http://emedicine.medscape.com/article/122958-overview#a1}}&lt;/ref&gt; [[Lecithin cholesterol acyltransferase deficiency|LCAT deficiency]] can cause impaired vision due to cholesterol corneal opacities, anemia, and kidney damage.&lt;ref&gt;{{Cite web|url=https://ghr.nlm.nih.gov/gene/LCAT|title=LCAT gene|last=Reference|first=Genetics Home|website=Genetics Home Reference|access-date=2016-12-11}}&lt;/ref&gt;<br /> <br /> ==Interactive pathway map==<br /> {{StatinPathway_WP430|highlight=Lecithin-cholesterol_acyltransferase}}<br /> <br /> ==See also==<br /> * [[Lecithin cholesterol acyltransferase deficiency]]<br /> * [[Sterol O-acyltransferase|Acyl-CoA:cholesterol acyltransferase]] (ACAT)<br /> <br /> ==References==<br /> {{Reflist|2}}<br /> <br /> ==Further reading==<br /> {{refbegin | 2}}<br /> * {{cite journal |vauthors=Dobiásová M, Frohlich J | title = Advances in understanding of the role of lecithin cholesterol acyltransferase (LCAT) in cholesterol transport. | journal = Clin Chim Acta | volume = 286 | issue = 1–2 | pages = 257–71 | year = 1999 | pmid = 10511297 | doi = 10.1016/S0009-8981(99)00106-0}}<br /> *{{cite journal |vauthors=Kuivenhoven JA, Pritchard H, Hill J, etal |title=The molecular pathology of lecithin:cholesterol acyltransferase (LCAT) deficiency syndromes |journal=J.
