Migraine is the most common type of chronic, episodic headache, as summarized by Featherstone (1985). One locus for migraine with or without aura (MGR1) has been identified on chromosome 4q24. Other loci for migraine have been identified on 6p21.1-p12.2 (MGR3; 607498), 14q21.2-q22.3 (MGR4; 607501), 19p13 (MGR5; 607508), 1q31 (MGR6; 607516), 15q11-q13 (MGR7; 609179), 5q21 (with or without aura, MGR8, 609570; with aura, MGR9, 609670), 17p13 (MGR10; 610208), 18q12 (MGR11; 610209), 10q22-q23 (MGR12; 611706), and the X chromosome (MGR2; 300125). Mutation in the KCNK18 gene (613655) on chromosome 10q25 causes migraine with aura (MGR13; 613656). A subtype of autosomal dominant migraine with aura (MA), familial hemiplegic migraine (FHM; see 141500), is caused by mutation in the CACNA1A gene (601011) on chromosome 19p13 (FHM1; 141500), by mutation in the ATP1A2 gene (182340) on chromosome 1q21 (FHM2; 602481), or by mutation in the SCN1A gene (182389) on chromosome 2q24 (FHM3; 609634). Another locus for FHM has been mapped to chromosome 1q31 (FHM4; see 607516). There is evidence that a polymorphism in the estrogen receptor gene (ESR1; 133430.0005) and a polymorphism in the TNF gene (191160.0004) may confer susceptibility to migraine. A polymorphism in the endothelin receptor type A gene (EDNRA; 131243.0001) may confer resistance to migraine. [from OMIM]
