FADS2

Encodes an enzyme involved in fatty-acid metabolism.

FTO

FTO is studied in relation to body weight and energy balance. Common variants can contribute to population-level differences in obesity susceptibility, alongside many other genes and environmental factors.

G6PC2

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.

GGH

GGH encodes gamma-glutamyl hydrolase, which removes glutamate residues from folate compounds. This affects folate handling and helps explain why folate metabolism includes retention and processing as well as intake.

IL6

IL6 encodes interleukin-6, a cytokine involved in immune responses and acute-phase signaling. It can appear in discussions of infection, chronic inflammation and metabolic health, with effects that depend on the context.

MTHFD1L

The homocysteine chapters include MTHFD1L in the wider folate-related genetic map.

Gene referenceSep 23, 2026

ALPL

ALPL encodes tissue-nonspecific alkaline phosphatase, an enzyme important to bone and tooth mineralization and vitamin B6 metabolism. Persistently low alkaline phosphatase can deserve a different evaluation from a general nutrient deficiency.

Gene referenceSep 23, 2026

IL18

IL18 encodes interleukin-18, a cytokine that can promote interferon-gamma responses in the appropriate immune context. Its receptor includes components encoded by IL18R1 and IL18RAP.

The Master MTHFR Protocol Dr. Purser Designed

Your local doctor will likely tell you that MTHFR testing and taking an MTHFR Daily supplement is a waste of money. They might even claim it isn't a real medical issue. After 15 years of hearing this pap, I can tell you they are flat-out wrong . Every day that I run into abject medical ignorance—where medicine arrogantly refuses to bend to the hard truth of proven science—I remember Ignaz Semmelweis. Semmelweis died a broken pauper in an asylum, his life destroyed by the conventional doctors of his generation who refused to accept handwashing. Their dismissive attitude today stems not from mal

Vitamin B9 / folate deficiency

Explore folate, vitamin B9, one-carbon metabolism, anemia, homocysteine, SLC19A1, and differences between folate forms and transport pathways.
