Abstract
Migraine is a neurological disorder that manifests as a debilitating headache associated with an altered sensory perception. It has classically been attributed to multifactorial etiologies, with genetic components and environmental interactions considered to be major influences. The neuropeptide calcitonin gene-related peptide (CGRP), flavoenzyme 5,10-methylenetetrahydrofolate reductase (MTHFR), and estrogen play key roles in migraine. In addition, receptor activity modifying protein 1 (RAMP1) is the primary receptor subunit of CGRP and plays a critical role in migraine. However, variations in the RAMP1 gene have not been found to be associated with migraine. Nevertheless, vitamins B6, B9, and B12 and MTHFR play vital roles in both methionine biosynthesis and DNA methylation. Higher levels of homocysteine are attributed to lower levels of estrogen among migraine patients. This chapter elucidates the genetic and epigenetic roles of CGRP, MTHFR, and estrogen in the pathophysiology of migraine.
