Your DNA file reports your genotype at rs7903146 — a marker in the TCF7L2 gene that studies link to type 2 diabetes risk (tcf7l2). Here's what each genotype is associated with:
| Genotype | What it's associated with |
|---|---|
| CC | Lower-risk genotype at TCF7L2, the strongest common type-2-diabetes marker — average background risk here. |
| CT | One risk (T) allele — modestly higher type-2-diabetes risk than average. Strongly modifiable by weight, diet and activity. Not a diagnosis. |
| TT | Two risk (T) alleles — higher type-2-diabetes risk at this marker (roughly double the C/C background). Largely modifiable by lifestyle; informational, not a diagnosis. |
