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…
GSR encodes glutathione reductase. It uses reducing power from NADPH to help convert oxidized glutathione back to reduced glutathione, allowing this antioxidant system to be reused.
Also called: Glutathione Reductase
Recycling used glutathi…
GSTM1 helps your body use glutathione to process some compounds.
Also called: Glutathione S-Transferase Mu 1
Using glutathione in conjugation
GSTM1 belongs to the glutathione transferase family. These enzymes use glutathione in conjugation …
GSTP1 helps your body use glutathione to process some compounds.
Also called: Glutathione S-Transferase Pi 1
Using glutathione in conjugation
GSTP1 belongs to the glutathione transferase family. These enzymes use glutathione in conjugation …
GSTT1 helps your body use glutathione to process some compounds.
Also called: Glutathione S-Transferase Theta 1, GSTT
Using glutathione in conjugation
GSTT1 belongs to the glutathione transferase family. These enzymes use glutathione in con…
HLA-DQA1 contributes to an HLA-DQ protein that presents antigen fragments to CD4 T cells. HLA-DQ function depends on pairing with an HLA-DQB chain, so an isolated marker is not a complete HLA type.
Also called: HLADQA1, Human Leukocyte Anti…
HLA-DQA2 is part of the HLA class II region involved in immune recognition. It should not be treated as interchangeable with HLA-DQA1 or as a measurement of how well the immune system fights infections.
Also called: HLADQA2, Human Leukocyte…
HRH2 is the gene name for Histamine Receptor H2. Learn what a specific result could mean and what to ask about it.
Also called: Histamine Receptor H2
Histamine also connects to stomach acid
Dr. Purser’s genetics reference connects HRH2 with…
MAOA helps break down some chemical messengers. A gene result cannot predict a mood or behavior.
Also called: MAO-A, Monoamine Oxidase A
Neurotransmitter breakdown in context
Dr. Purser places MAOA in the neurotransmitter-breakdown part of …
MMP3 encodes matrix metalloproteinase 3, an enzyme involved in breaking down components of the extracellular matrix. Controlled remodeling is part of repair, while excess activity can accompany inflammatory tissue damage.
Also called: Matri…
Makes the methionine synthase enzyme, which uses vitamin B12 in the conversion of homocysteine to methionine.
Also called: Methionine Synthase
The B12-dependent step
In Dr. Purser’s teaching map, MTR is the B12-dependent step that converts …
NAT2 encodes N-acetyltransferase 2, which helps process certain drugs and other compounds. Combinations of variants can influence acetylation status; one SNP usually does not tell the entire story.
Also called: N-Acetyltransferase 2
Acetyla…
