STAT6 and migraine disorder: Of these, rs167769 is both associated with migraine and an sQTL associated with an alternative 5’ splice site in the first exon of five of the six annotated transcripts of STAT6. This splicing variation affects the 5’ UTR (sQTL FDR = 0.047) and accounts for approximately 7% increase in inclusion of the 18-nt extension (S3 Table and S3 Fig).
