There is one clinical trial.
The investigators hypothesized that migraine without patients with many genetic loci associated with migraine (high genetic load) would be more sensitive and get provoked more migraine attacks by calcitonin gene-related peptide (CGRP) compared to patients with few genetic loci associated with migraine (low genetic load).
One of the genetic loci (rs13208321) is located in a gene (FHL5) that is associated with the regulation of cAMP-responsive elements.
Description: The difference in incidence of migraine-like attacks between patients with high genetic load and patients with low genetic load using verbal rating scale (VRS).
Measure: CGRP induced migraine attacks in patients with high and low genetic load Time: Change from baseline in headache intensity at 12 hours after the start of infusion of CGRPDescription: The difference in area under the curve (AUC) for headache intensity scores (0-12 hours)
Measure: CGRP induced migraine attacks in patients with high and low genetic load Time: Change from baseline in headache intensity at 12 hours after the start of infusion of CGRP
