Type Excerpt DOI
Functional "PCSK9 reduces the hepatic uptake of atherosclerosis-promoting low density lipoproteins (LDL) by targeting the LDL receptor for degradation (99)." 10.1093/nargab/lqz012
Mutation Description "PCSK9 is lost in at least six independent lineages totaling 20 mammals and CETP is lost in at least four independent lineages comprising a total of 33 mammals in our dataset (Figure 2A; Supplementary Figures S8 and S9)." 10.1093/nargab/lqz012
Timing of Loss "Exon 6 has a 1 bp frameshifting deletion that is shared across almost species. The respective region was presumably later deleted in the cat and Weddell seal." see supplementary material" 10.1093/nargab/lqz012
Other "While PCSK9 gain-of-function mutations cause hypercholesterolemia (100,101), loss-of function mutations in the human or mouse gene result in low LDL cholesterol levels (96,102–104)." 10.1093/nargab/lqz012
Other "Interestingly, many mammals have lost both PCSK9 and CETP." 10.1093/nargab/lqz012
