Let’s explore “Low hemoglobin A1C: interpreting the result”

HDC is the gene name for Histidine Decarboxylase. Learn what a specific result could mean and what to ask about it.

HRH1 is the gene name for Histamine Receptor H1. Learn what a specific result could mean and what to ask about it.

HRH2 is the gene name for Histamine Receptor H2. Learn what a specific result could mean and what to ask about it.

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

NQO1 is the gene name for NAD(P)H Quinone Oxidoreductase 1. Learn what a specific result could mean and what to ask about it.

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

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.

VDR encodes the vitamin D receptor, which helps regulate gene activity in response to active vitamin D. A receptor variant does not by itself mean receptors are absent or that the blood vitamin D level is low.

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 deficiency.

F9 encodes coagulation factor IX. Disease-causing variants can result in hemophilia B, an inherited bleeding disorder, but a panel marker is not equivalent to a confirmed disease-causing finding.

IL2RA encodes the alpha chain of the interleukin-2 receptor, also called CD25. It is involved in immune activation and regulatory T-cell biology; a soluble receptor measurement is distinct from a DNA result.

ACE is the gene name for Angiotensin-Converting Enzyme. Learn what a specific result could mean and what to ask about it.
