Diastolic blood pressure association
Blood pressure between heartbeats, the lower of the two numbers.
What the research found
In the cited research, the T allele at rs13082711 was associated with lower diastolic blood pressure in the studied cohorts.
- CC
- Higher average
- CT
- Middle
- TT
- Lower average
What the study found
In the study, each copy went with diastolic blood pressure about 0.24 mmHg lower on average.
- Evidence
- Genome-wide association with independent follow-up
- Who was studied
- European-ancestry discovery and independent follow-up cohorts

- C and T, with T as the studied allele
A DNA Traits report reads this marker in your raw DNA file and shows which of the three genotypes is yours, with how common it is. It counts the copies of the studied allele; it does not measure the trait itself.

What it cannot tell you
The average per-allele difference in the research cohorts was less than 1 mmHg. This marker cannot tell you your current blood pressure, is not a test for high or low blood pressure, cannot calculate cardiovascular risk and does not guide treatment. Only the studied C/T allele pair is interpreted.
