CRP
One position in this gene is readable from a home DNA test.
Your baseline C-reactive protein

CRP is the inflammation marker most often measured in a blood test. Part of your baseline is genetic rather than a reflection of how inflamed you are, which matters when a doctor reads the number.
| If you carry | What it means |
|---|---|
| No copies | You have the higher-CRP version on both copies |
| One copy | You carry one lower-CRP copy |
| Two copies | You have the lower-CRP version on both copies |
| Ancestry group | T (the effect version) | |
|---|---|---|
| African | 17.0% | |
| American | 37.5% | |
| East Asian | 56.6% | |
| European | 31.0% | |
| South Asian | 33.3% |
1000 Genomes Project phase 3, via Ensembl, retrieved 2026-09-23. These groupings are coarse and flatten a great deal of internal diversity, particularly within Africa. A variant being common somewhere tells you where a piece of your ancestry probably comes from, and nothing else.
