Let’s explore “Environmental exposure, inflammation, and transsulfuration questions”

MAOA helps break down some chemical messengers. A gene result cannot predict a mood or behavior.

MTHFD1 helps move folate between forms used for different jobs in the body.

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

Makes an enzyme that helps produce a form of folate used in the processing of homocysteine. Common variants are different from rare variants that cause severe MTHFR deficiency.

Makes the methionine synthase enzyme, which uses vitamin B12 in the conversion of homocysteine to methionine.

Helps maintain the activity of methionine synthase, connecting B12-related chemistry with homocysteine metabolism.

Makes an enzyme involved in producing phosphatidylcholine, a component of cell membranes. Genetic findings alone do not establish a choline deficiency.

SHMT1 connects serine and glycine with folate chemistry.

SOD1 helps convert superoxide inside cells as part of the body’s antioxidant defenses.

SOD2 works in mitochondria as part of the body’s antioxidant defenses.

SOD3 works outside cells as part of the body’s antioxidant defenses.

TCN2 helps carry vitamin B12 in the body. A gene result alone cannot tell you your B12 status.
