LDL cholesterol concentration association
The blood level of LDL cholesterol.

What the research found
In the cited research, the T allele at rs12740374 was associated with lower blood LDL cholesterol concentrations in the studied cohorts.
- GG
- Higher average
- GT
- Middle
- TT
- Lower average
What the study found
In the study, each copy went with lower LDL cholesterol on average.
- Evidence
- Genome-wide association at an established lipid locus
- Who was studied
- European-ancestry participants across multiple research cohorts

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
This is an association with a blood lipid measurement, not an estimate of your current lipid level. A single marker is not a test for high cholesterol, cannot predict heart attack or stroke risk and does not guide diet, medication or treatment. Only the studied G/T allele pair is interpreted.
Common variants at 30 loci contribute to polygenic dyslipidemia (Kathiresan et al., 2009)More in Heart & circulation
