A recent genome-wide association study (GWAS) provides new insights into the genetic basis of childhood migraine and allows for precision therapeutic development strategies targeting migraine patients of African-American ancestry. Researchers conducted a GWAS of 380 African-American children and 2129 ancestry-matched controls to identify variants associated with migraine. They then attempted to replicate their primary analysis in an independent cohort of 233 African-American patients and 4038 non-migraine control subjects. They found:
- Common variants at 5q33.1 are associated with migraine risk in African-American children.
- The association was validated in an independent study for an overall meta-analysis P-value of 3.81×10−10.
- eQTL (expression quantitative trait loci) analysis of the Genotype-Tissue Expression data also shows the genotypes of rs72793414 were strongly correlated with the mRNA expression levels of NMUR2 at 5q33.1.
