ADIPOQ

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.

Gene referenceSep 23, 2026

BCO1

BCO1, also called BCMO1, helps convert beta-carotene from plant foods into retinal, a form used in vitamin A metabolism. Plant carotenoids and preformed vitamin A therefore enter the pathway at different points.

DHFR

DHFR helps reduce folic acid and dihydrofolate to tetrahydrofolate-related forms used in cellular metabolism. This is one part of the folate system, distinct from MTHFR and folate transport into cells.

Gene referenceSep 23, 2026

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.

Gene referenceSep 23, 2026

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.

Gene referenceSep 23, 2026

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.

Gene referenceSep 23, 2026

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.

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.
