Human and mouse KIAA0408 are 53.531% similar and have 149 similar positions. There is a large region that is missing in mouse in the C-terminus, and another smaller chunk missing in the N-terminus. This could be an evolutionary sign of humans’ erroneous development of more genes to make them more complex individuals. The areas before and after both deletions are highly conserved, so these are likely very critical regions of the gene.
