What’s searchable?Makes an enzyme involved in producing phosphatidylcholine, a component of cell membranes. Genetic findings alone do not establish a choline deficiency. Also called: Phosphatidylethanolamine N-Methyltransferase, choline, phosphatidylcholine …
PSEN2 encodes a presenilin protein that participates in gamma-secretase, a protein-processing complex. Some pathogenic variants can cause familial Alzheimer’s disease; a listed common marker is not equivalent to that diagnosis. Also called:…
PTGS2, commonly called COX-2, encodes an enzyme involved in prostaglandin production. Prostaglandins participate in pain, fever and inflammatory signaling. Also called: COX2, Cyclooxygenase 2 COX-2 and inflammatory prostaglandins PTGS2, com…
Dr. Also called: Superoxide Dismutase 2 Superoxide defense in its own setting Dr. Purser teaches SOD as one member of an antioxidant team. SOD2 works in mitochondria and uses manganese. SOD converts superoxide into hydrogen peroxide, which …
Dr. Also called: Superoxide Dismutase 3 Superoxide defense in its own setting Dr. Purser teaches SOD as one member of an antioxidant team. SOD3 works outside cells and uses copper and zinc. SOD converts superoxide into hydrogen peroxide, wh…
TCN2 appears in Dr. Also called: Transcobalamin II B12 must be carried as well as consumed TCN2 appears in Dr. Purser’s homocysteine and methylation map because it concerns the transport of B12. The teaching distinction is between eating or…
TNF encodes tumor necrosis factor, an immune-signaling protein involved in inflammation, host defense and regulation of cell survival. Its name should not be read as proof that a TNF result indicates cancer. Also called: Tumor Necrosis Fact…
Separate the gene, variant, measured value and clinical interpretation—and learn which questions to bring to your visit. Also called: Keep the original result in view The uploaded SOPs begin with source verification: the right report, date…

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 deficienc…
CCL5, also called RANTES, is a chemokine that helps direct immune-cell movement. Chemokines tell cells where to go, which is different from measuring the total strength of an immune response. Also called: RANTES and immune-cell recruitment…
CD40 encodes a receptor that participates in communication between immune cells, including T-cell help for B-cell responses. Its partner is CD40 ligand, encoded by CD40LG. Also called: A conversation between immune cells CD40 encodes a rec…
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.
