Genetic and MTHFR testing in McKinney turns a confusing internet search into a clear plan. Thousands of people in Dallas–Fort Worth look up “MTHFR mutation” every month, usually after a result they don’t know what to do with.
Methylation, in plain English
Methylation is a reaction your body runs constantly. It supports detox, builds mood chemicals like serotonin and dopamine, clears used estrogen and keeps homocysteine, a heart-risk marker, in range. When it slows down, people often notice fatigue rest doesn’t fix, brain fog, anxiety or low mood, poor sleep, and sensitivity to chemicals or medications.
What the test looks at
A cheek swab or saliva sample checks genes tied to methylation, detox, oxidative stress, neurotransmitters and vitamin metabolism, including MTHFR, COMT, MTR and MTRR.
Genes plus lifestyle: your real picture
Genes describe tendencies, not destiny. Dr. Cas pairs your results with markers like homocysteine and B-vitamin status, then matches the plan to your biology: the right forms of folate and B12, the right pace of methylation support (too much too fast can backfire), and detox support that fits your capacity.
