Recently two independent research groups published scientific papers providing evidence that a genetic variation associated with Alzheimer’s may also be affecting the severity of pathology in Parkinson’s.
The genetic variation associated with Alzheimer’s occurs in a gene (a functional region of DNA) called ApoE, and the Parkinson’s pathology involves the clustering of a protein called alpha synuclein.
Specifically, both researchers reported that a genetic variation called ApoE4 is associated with higher levels of alpha synuclein clustering. And ApoE4 is also associated with worse cognitive issues in people carrying it.
In today’s post, we will discuss what ApoE is, what is known about ApoE4, what these new studies found, and what it could mean for the future treatment of Parkinson’s and associated conditions.

When I say the word ‘mutant’, what do you think of?
Perhaps your imagination drifts towards comic book superheroes or characters in movies who have acquired amazing new super powers resulting from their bodies being zapped with toxic gamma-rays or such like.
Alternatively, maybe you think of certain negative connotation associated with the word ‘mutant’. You might associate the word with terms like ‘weirdo’ or ‘oddity’, and think of the ‘freak show’ performers who used to be put on display at the travelling carnivals.

In biology, however, the word ‘mutant’ means something utterly different.
