Some defects in DNA might be able to be fixed with vitamins and minerals

“Our studies have convinced us that there is a lot of variation in the population in these enzymes, and a lot of it affects function, and a lot of it is responsive to vitamins,” Marini said. “I wouldn’t be surprised if everybody is going to require a different optimal dose of vitamins based on their genetic makeup, based upon the kind of variance they are harboring in vitamin-dependent enzymes.” . . .

“Our soldiers, like top athletes, operate under extreme conditions that may well be limited by their physiology,” Rine said. “We’re now working with the defense department to identify variants of enzymes that are remediable, and ultimately hope to identify troops that have these variants and test whether performance can be enhanced by appropriate supplementation.” . . .

Since this experiment, the researchers have found 30 other variants of the MTHFR enzyme and tested about 15 of them, “and more than half interfere with the function of the enzyme, producing a hundred-fold range of enzyme activity. The majority of these can be either partially or completely restored to normal activity by adding more folate. And that is a surprise,” Rine said. . .

Most scientists think that harmful mutations are disfavored by evolution, but Rine pointed out that this applies only to mutations that affect reproductive fitness. Mutations that affect our health in later years are not efficiently removed by evolution and may remain in our genome forever. . .

“There are over 600 human enzymes that use vitamins or minerals as cofactors, and this study reports just what we found by studying one of them,” Rine said. “What this means is that, even if the odds of an individual having a defect in one gene is low, with 600 genes, we are all likely to have some mutations that limit one or more of our enzymes.”

The subtle effects of variation in enzyme activity may well account for conflicting results of some clinical trials, including the confusing data on the effect of vitamin supplements, he noted. In the future, the enzyme profile of research subjects will have to be taken into account in analyzing the outcome of clinical trials. . .
