— MEF2D
Intronic variant in MEF2D encoding a key neuronal transcription factor that regulates excitatory synapse development and neuronal survival; the C allele is associated with increased migraine susceptibility in the largest migraine GWAS to date (OR=1.075, P=3.0E-41, 102,084 cases) and is thought to subtly alter MEF2D expression in cortical and trigeminal neurons, modulating synaptic excitability thresholds
