Lymphocyte count association
The number of lymphocytes, the white blood cells that include T cells and B cells, in the blood.
What the research found
In the cited research, the A allele at rs11878602 was associated with lower lymphocyte counts in the studied 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 small association is with a laboratory blood-cell count within the normal range studied. It does not estimate your current count, grade immune strength or predict infection, allergy, autoimmune disease or blood cancer. Only the studied A/C allele pair is interpreted.
