ESR1

Some search terms matched

ESR1 encodes estrogen receptor alpha, which helps cells respond to estrogen. Receptor signaling is different from the amount of estrogen measured in blood. Also called: Estrogen Receptor 1 Estrogen signaling depends on the receptor ESR1 enc…

FOLH1

Some search terms matched

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…

FOLR1

Some search terms matched

FOLR1 encodes folate receptor alpha, which helps cells take up folate and has an important role in folate transport at the brain’s barriers. Blood folate and folate availability in the nervous system are not identical measurements. Also cal…

FOLR2

Some search terms matched

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 …

FTO

Some search terms matched

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. Also called: Fat Mass and Obesity-…

FUT2

Some search terms matched

FUT2 affects substances on the surfaces of the gut and other moist tissues and is studied in relation to the microbiome. Also called: Fucosyltransferase 2 The mucosal and microbiome connection Dr. Purser’s course places FUT2 in its gut–immu…

G6PC2

Some search terms matched

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…

GAD1

Some search terms matched

GAD1 helps your body make GABA, a chemical messenger, from glutamate. Also called: Glutamate Decarboxylase 1 The glutamate-to-GABA connection Dr. Purser’s course uses GAD/GABA teaching to explain a connection between excitatory and inhibito…

GAD2

Some search terms matched

GAD2 helps make GABA, a chemical messenger, from glutamate. Also called: Glutamate Decarboxylase 2 Another part of the GABA system GAD2 helps make GABA from glutamate. GAD1 does a related job, but the two genes are different. Check the exac…

GCLC helps make glutathione, an antioxidant your body produces. Also called: Glutamate-Cysteine Ligase Catalytic Subunit Making glutathione is a process Dr. Purser groups GCLC and GCLM as glutathione-synthesis machinery. GCLC supplies the c…

Best match puts all-term matches before partial matches and related reading. Identical social posts and matching long titles across other sources are grouped when access is the same. Search covers published titles, descriptions, available article text, report overviews, and the full text of the nutrient, gene and learning-essential reference pages. Books, uploaded chapters and downloads-page reports are searchable through selected editorial guides and topic names; the original files and full book text are not published. Full Drive reports are not copied into search. Substack subscriber titles and public summaries are included; full subscriber content opens on Substack. Video transcripts are added when available.
