Your DNA file reports your genotype at rs2200733 — a marker in the 4q25 (PITX2) gene that studies link to atrial fibrillation risk (4q25). Here's what each genotype is associated with:
| Genotype | What it's associated with |
|---|---|
| CC | Lower-risk genotype at the 4q25/PITX2 locus, the top common atrial-fibrillation marker — average background risk. |
| CT | One risk (T) allele — modestly higher atrial-fibrillation risk. Informational; mention palpitations to your doctor if they occur. |
| TT | Two risk (T) alleles — higher atrial-fibrillation risk at this marker. Informational, not a diagnosis. |
