MAOA helps break down some chemical messengers. A gene result cannot predict a mood or behavior. Also called: MAO-A, Monoamine Oxidase A Neurotransmitter breakdown in context Dr. Purser places MAOA in the neurotransmitter-breakdown part of …

What’s searchable?Makes the methionine synthase enzyme, which uses vitamin B12 in the conversion of homocysteine to methionine. Also called: Methionine Synthase The B12-dependent step In Dr. Purser’s teaching map, MTR is the B12-dependent step that converts …
NAT2 encodes N-acetyltransferase 2, which helps process certain drugs and other compounds. Combinations of variants can influence acetylation status; one SNP usually does not tell the entire story. Also called: N-Acetyltransferase 2 Acetyla…
NR3C1 encodes the glucocorticoid receptor, which helps tissues respond to cortisol and glucocorticoid medicines. Receptor genetics and measured cortisol levels answer different questions. Also called: Nuclear Receptor Subfamily 3 Group C Me…
NR3C2 encodes the mineralocorticoid receptor, which responds to hormones such as aldosterone and helps regulate salt and fluid balance. It is distinct from the NR3C1 glucocorticoid receptor. Also called: Mineralocorticoid Receptor / Nuclear…
NTRK2 encodes TrkB, a receptor involved in responding to neurotrophic signals such as BDNF. These signals support nervous-system function and plasticity. NTRK2 is not a phosphatidylserine absorption transporter. Also called: Neurotrophic Re…
Makes an enzyme involved in producing phosphatidylcholine, a component of cell membranes. Genetic findings alone do not establish a choline deficiency. Also called: Phosphatidylethanolamine N-Methyltransferase, choline, phosphatidylcholine …
PON1 is discussed in relation to how the body handles some compounds and protects certain fats. Also called: Paraoxonase 1 A different part of antioxidant handling PON1 appears in Dr. Purser’s redox and conversion teaching alongside GST and…
TCN2 helps carry vitamin B12 in the body. A gene result alone cannot tell you your B12 status. Also called: Transcobalamin II B12 must be carried as well as consumed TCN2 appears in Dr. Purser’s homocysteine and methylation map because it c…
VDR encodes the vitamin D receptor, which helps regulate gene activity in response to active vitamin D. A receptor variant does not by itself mean receptors are absent or that the blood vitamin D level is low. Also called: Vitamin D Recepto…
VKORC1 encodes vitamin K epoxide reductase, part of the vitamin K recycling system used in activating clotting proteins. It is not simply a vitamin K receptor. Also called: Vitamin K Epoxide Reductase Complex Subunit 1 Recycling vitamin K a…
How the Purser approach moves from a nutrient finding to priorities, a manageable plan and reassessment. Also called: From a laboratory flag to a useful plan Start with your original CMA report: check its date, values, and the lab’s catego…
About search coverage
Search looks for your words in titles, descriptions, available articles, learning guides, and video captions when available. The closest matches appear first. Duplicate posts are grouped, with links to other places you can read or watch them. Books, chapters, and reports have topic guides here; the original files and full book text are not available in this encyclopedia.
