Helps calcium absorption and bone mineralization.
Also called: Vitamin D
A nutrient level and a receptor gene answer different questions
Dr. Purser places vitamin D in immune, hormone and bone-related teaching. The conversion-genetics chapt…
A carotenoid found in foods and in the retina.
Also called: Zeaxanthin
What it does
A carotenoid found in foods and in the retina.
How supplementation is approached
Zeaxanthin is a plant pigment found in the eye and often paired with lutein…
Supports enzymes, immune function, wound healing and taste.
Also called: Zinc
Read zinc together with copper
Zinc connects with immune function, hormones, copper handling and antioxidant enzymes. A plan for zinc should also account for othe…
ADIPOQ encodes adiponectin, a hormone released by fat tissue that participates in insulin sensitivity and fat metabolism. Its name often appears in discussions of triglycerides, body composition and metabolic health.
Also called: Adiponecti…
APOE encodes a protein that carries lipids between cells. The familiar APOE e2, e3 and e4 groupings depend on the combination of rs429358 and rs7412, not on either marker read in isolation.
Also called: Apolipoprotein E
Lipid transport and …
BHMT helps recycle homocysteine into methionine using betaine. It is a different route from the folate and B12 pathway.
Also called: BHMT08, Betaine-Homocysteine S-Methyltransferase
Another route through the homocysteine map
BHMT is part of…
CD14 helps immune cells recognize microbial components, including bacterial lipopolysaccharide, as part of innate immune signaling. This places it upstream of some cytokine responses.
Also called: Cluster of Differentiation 14
How immune ce…
COL5A1 encodes one component of type V collagen, which helps organize collagen fibers. It connects to the strength and structure of tendons, skin and other connective tissues.
Also called: Collagen Type V Alpha 1 Chain
Collagen structure, t…
The older Purser genetics reference uses the heading “DAOA (AOC1)” in its gut section.
Also called: D-Amino Acid Oxidase Activator
Two similar names, two different pathways
You may see DAOA and AOC1 written together in older materials, but …
FOLH1 helps break down folate from food so it can be absorbed. This is different from the MTHFR step.
Also called: Folate Hydrolase 1
Folate handling begins before remethylation
Dr. Purser’s genetic chapters include FOLH1 in folate handling…
FOLR2 encodes folate receptor beta, a folate-binding protein expressed in particular cell types, including subsets of immune cells. It is distinct from the FOLR1 receptor and the SLC19A1 reduced folate carrier.
Also called: Folate Receptor …
G6PC2 encodes a glucose-6-phosphatase-related protein expressed in pancreatic islet cells. Common variation is associated with differences in fasting glucose regulation; it is not the insulin receptor.
Also called: Glucose-6-Phosphatase Cat…
