I also have polymorphism in my melatonin, receptor genetics that are linked to this disorder. But I have several other genetics that make this a definite polygenic disease. So I highly doubt chronology efforts are going to work in a holistic way.
My heritage is from the Sami people of Finland. And my disorder is most likely related to that heritage and my sensitivity to light changes. But also changes in my diet. Specifically higher omega-3 fatty acids, and I mean really high.
