Type Excerpt DOI
Functional "CETP transfers cholesteryl ester from high-density lipoproteins (HDCs) to LDLs in exchange for triglycerides (105)." 10.1093/nargab/lqz012
Mutation Description "... 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
Mutation Description "The entire gene appears to be absent from the genomes of the hedgehog and shrew, and the respective unaligning regions that are flanked by up- and downstream aligning blocks are markedly shorter than in human, which is consistent with a larger deletion. However, the respective region overlaps an assembly gap in both species, therefore an upgraded genome assembly is required to confirm the loss of CETP in hedgehog." and shrew." 10.1093/nargab/lqz012
Timing of Loss "The deletion of exons 14 and 15 is most likely shared between all Laurasiatheria species, indicating an ancestral gene loss." See supplementary material" 10.1093/nargab/lqz012
Phenotypic "Mutations in human CETP are associated with increased HDL cholesterol levels and reduced levels of the atherosclerosis-promoting LDL cholesterol (97,106)." 10.1093/nargab/lqz012
Other "Interestingly, many mammals have lost both PCSK9 and CETP." 10.1093/nargab/lqz012

Curator Observations

Authors are uncertain about gene loss in this species due to genome assembly gaps see mutation description statements.
