Common variants in KCNK5 and FHL5 genes contributed to the susceptibility of migraine without aura in Han Chinese population

Abstract A recent genome-wide meta study suggested that rs67338227 in the FHL5 gene and rs10456100 in the KCNK5 gene are associated with migraine from 27 population-based cohorts excluding Chinese population. Given that migraine without aura (MO) is the most common subtype of migraine, our aim was t...
