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.

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

The Purser genetics reference places HRH1 in the histamine-…
…stamine also connects to stomach acid
Dr. Purser’s genetics reference connects HRH2 with histamine signaling and gastric acid secretion. H2 is a receptor, so this teaching concerns response to a signal rather than histamine production by HD…
IL21 encodes a cytokine involved in regulating lymphocytes, including B-cell responses. It sits within an immune network that connects T-cell help, antibody responses and inflammatory activity.
