Interesting connection with brain complexity, but note that the function of the Huntinton's gene remains poorly understood. Something that may be related... The same unstable repeat that causes the disease is ancient and is conserved throughout mammals! So other mammals can get a similar disease driven by the same mutations. This is useful for generating models of the disease in other mammals (e.g. mice). Such conservation of repeats is exceptionally rare.
