As far as I know yes, but I do not see the significance if it were the only known example. Genome sequencing is a relatively new discipline and it requires detailed analysis to identify such a mutation. The fusion in chromosome 2 was found because it was being focused on due to its size and as an explanation for the chromosomal number difference between us and other apes.
If we targeted other species we may find others. I suspect we would because chromosomal number differences are not unusual between closely related species - the reason must be fusion or separation.
Sorry I cannot be more help.
