Learn about the interferon and IL-15 pathways described in this teaching.

Learn how eosinophils and type 2 immune signals are discussed in this teaching.

Lichen planus can affect skin, mouth, nails, and other surfaces.

This variant is in a regulatory region of the TNF gene.

This inflammatory condition affects the esophagus.

This immune-mediated condition can affect the optic nerves and spinal cord.

Coming soon: the DRP Genetic Cytokine Panel. This panel looks at 90 different cytokine gene SNPs. If even one of those SNPs is homozygous, it can drive major inflammatory issues that never fully settle with standard care. If you have unex

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.

KIT encodes a receptor tyrosine kinase that responds to stem cell factor. It participates in blood-cell development and mast-cell biology, making the exact variant and testing context especially important.

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.

C3 is the gene name for Complement C3. Learn what a specific result could mean and what to ask about it.
