I’ve had a chronic, mild elevation of serum tryptase, a marker for mast cell activation, for more than 5 years. It may be a sign of Mast Cell Activation Syndrome, in which serum tryptase is generally normal until there’s a triggering episode or slightly elevated like this.
Thanks to the DNA Methylation Pathway with Methylation Pathways Analysis test, which identifies genetic mutations on this critical biochemical pathway, I now understand one possible reason for this elevation.
Mutations on the Methylation Pathyway
The biochemical process of methylation, which takes place in our bodies millions of times each day, is consider the backbone of our physiology. One of the best explanations of methylation has been offered by Dr. Young on his Methyl Cycle NutriGenomis page. According to Dr. Young, methylation will be of special interest to those with certain chronic illnesses. He says:
“…individuals harboring Methyl Cycle Defects are going to get sick, before their time, likely with conditions that make little sense such as Fibromyalgia, Chronic Fatigue, Multiple Chemical Sensitivity, or they will present early in life with what used to be diseases seen only in “old people”: – coronary disease, cardiomyopathy, Parkinson’s disease, and dementia.”
There are many different methyl cycle mutations, and it all depends on whether the mutations are expressed or not. But, if you have chronic illnesses like the ones above, there’s a good chance they are. And, the good news is that you might be able to workaround the mutations, and recover some degree of your health.
The CBS Gene and the Mast Cell Connection
CBS C699T and/or A360A up regulations are two that can especially play havoc in your body. In fact, CBS mutations as well as SUOX and NOS mutations must be addressed before you can effectively address any other methyl cycle mutations.
While there are several different adverse impacts of these CBS up regulations, one is the accumulation of excess ammonia. The increased ammonia depletes BH4, which may lead to mast cell degranulation and excess histamine. Bingo!
It looks like this might explain my chronic elevation of serum tryptase, and slightly leaky mast cells, which keep me in a state of mild allergy-like response. Does the CBS polymorphism explain Mast Cell Activation Syndrome? That’s difficult to say as there may be other factors involved as well. We’ll have to wait until research discovers a definitive answer to that question.
Managing CBS Up Regulations
A low protein diet constitutes a key antidote to the CBS up regulations because protein contains significant amounts of ammonia adding to your already burdened system. Some doctor’s restrict animal protein entirely. Other doctors advise you to limit animal protein to no more than 3 ounces a day, and to sprinkle it with yucca root, which decreases the amount of ammonia your body will absorb. There are other important elements to the CBS protocol, but the restriction of dietary protein appears to be of utmost importance.
I’ve restricted animal protein for 5 days now. The difference is like night and day. I’ve felt a noticeable improvement in my energy, muscles and joints, and the whole feel of my body. I look forward to continuing on a no animal protein diet (or eating very little), and observing whether further changes occur.
Have you tried a low protein diet? Has it helped you?
