rs7904615
rs7904615 is a non-coding variant near ADARB2 (adenosine deaminase RNA specific B2) on chromosome 10, identified as the lead genome-wide significant signal for complete freedom from headache in a study of the Danish Blood Donor Study cohort (~64,000 individuals). The G allele was associated with roughly 20% higher odds of never having experienced a headache, an association specific to headache-free status rather than any migraine or headache-disorder diagnosis. It is used here as an exploratory novelty marker for headache-free tendency rather than a validated clinical or preventive variant.
