What’s searchable?Makes an enzyme that helps break down catechol compounds, including some neurotransmitters. A common variant does not by itself explain mood, attention or stress tolerance. Also called: Catechol-O-Methyltransferase Catecholamines and sensit…
CTH helps make cysteine, one of the building blocks your body uses to make glutathione. Also called: Cystathionine Gamma-Lyase From homocysteine toward glutathione Dr. Purser places CTH in the sulfur-handling pathway that connects homocyste…
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. Also called: Dihydrofolate Reductase R…
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…
Encodes an enzyme involved in fatty-acid metabolism. Also called: Fatty Acid Desaturase 1 / D5D The form of a fatty acid matters Dr. Purser teaches FADS genes as a conversion pathway. FADS1 participates in a delta-5 desaturase step in fatty…
Encodes an enzyme involved in fatty-acid metabolism. Also called: Fatty Acid Desaturase 2 / D6D The form of a fatty acid matters Dr. Purser teaches FADS genes as a conversion pathway. FADS2 participates in a delta-6 desaturase step in fatty…
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-…
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…
GCLM helps regulate one of the steps your body uses to make glutathione. Also called: Glutamate-Cysteine Ligase Modifier Subunit Making glutathione is a process Dr. Purser groups GCLC and GCLM as glutathione-synthesis machinery. GCLM suppli…
GDF5 encodes growth differentiation factor 5, a signaling protein involved in skeletal development, joint formation and cartilage biology. Its name does not mean a SNP measures the ability to build muscle. Also called: Growth Differentiatio…
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. Also called: Gamma-Gluta…
