Lean body mass association
The weight of everything in the body that is not fat, such as muscle and bone.

What the research found
In the cited research, the A allele at rs2287926 was associated with higher whole-body lean mass after adjustment for fat mass and height in the studied cohorts.
- GG
- Lower average
- AG
- Middle
- AA
- Higher average
What the study found
In the study, each copy went with whole-body lean mass after adjustment for height and fat mass about 0.19 kg higher on average.
- Evidence
- Genome-wide association with independent replication
- Who was studied
- European-ancestry discovery and replication 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
Lean mass includes non-fat soft tissues, including organs, as well as muscle. The study adjusted for height, fat mass, age and sex. This marker cannot tell you your current muscle mass, bodybuilding potential or response to training, and it is not a test for low muscle mass.
