Mutation Description "In Caniformia, traces of gradual gene degradation over evolutionary time could still be found when comparing the basal Canidae to more recent families (Fig. 4). Indeed, while Canidae typically lack only exons 3 and 5, two additional deletions caused the loss of exons 4, 7 to 9 and part of exon 10 after the UrsidaeCanidae split, as evidenced by the sequences of Ursidae, Pinnipedia and Ailuridae." 10.1007/s10709-021-00113-x
Mutation Description "In Feliformia, on the other hand, only exon 12 has been preserved in Felidae and Hyaenidae, while Viverridae also contained a fragment of exon 6, and Herpestidae and Eupleridae have retained exons 10 to 12 (ST2)." 10.1007/s10709-021-00113-x
Timing of Loss "In Carnivora, none of the 63 species analysed had a functional gene, but there was a marked difference in the pattern of gene inactivation between the suborders Caniformia and Feliformia." 10.1007/s10709-021-00113-x
Timing of Loss "Interestingly, all extant exon 12 sequences from Feliformia and Canidae (although not from other Caniformia) seemed to share a 5-bp insertion (Fig. 4), suggesting that PCSK9 inactivation took place before the Caniformia-Feliformia split and therefore very early in the evolution of Carnivora." 10.1007/s10709-021-00113-x

Curator Observations

Although all Carnivora analyzed presented a PCSK9 Pseudogene, no ancestral shared mutation was identified between Caniformia and Feliformia.
