>- I dont buy the gene link at all to any modern diseases
Well, I can say that the gene link is real, but, it is not a completely defective gene, it is a weak gene that needs vitamin D to strengthen it.
Many years ago in college, I learned that weak genes such as the one in question were very susceptible to small changes in the body, such as very minor pH changes as well as changes in the levels of hormones ( which BTW, vitamin D is ).
Sadly, the medical profession, through its greed and self serving nature, completely ignores this. This is nothing new as I posted in my Blog article about John Wesley and the use of Electrification as a cure. http://zapperdave.blogspot.com/
