| Mutation Description | "Cetacean species IL20 gene annotation revealed the presence of several ORF disrupting mutations, of note a single transversal mutation present in all analyzed species, namely the abolition of a canonical donor splice site in exon 1 (Fig. 2a)." | 10.1007/s00251-018-1071-5 |
| Timing of Loss | "The sharing of a single conserved mutation in the donor splice site (GT>CT) of exon 1, along with the high ω rate calculated for the ancestral branch of cetaceans, suggests that IL20 pseudogenization occurred in the ancestor of whales and dolphins approximately 34 MYA (Pyenson 2017)." | 10.1007/s00251-018-1071-5 |
Curator Observations
Given the conservation of the LoF mutation in all cetacea including Balaena mystecetus , and although genomic information is avaliable for this species we can safely assume that the loss in this lineage Full in other words affects all individuals.
