Genome wide association study identifies variants in NBEA associated with migraine in bipolar disorder

Abstract: Background Migraine is a common comorbidity among individuals with bipolar disorder, but the underlying mechanisms for this co-occurrence are poorly understood. The aim of this study was to investigate the genetic background of bipolar patients with and without migraine. Methods We performed a genome-wide association analysis contrasting 460 bipolar migraneurs with 914 bipolar patients without migraine from the Bipolar Genome Study (BiGS). Results We identified one genome-wide significant association betwe… Show more

“…Recently, the SNP rs1160720 (near NBEA on 13q13.3) was found to be significantly associated with comorbid bipolar disorder and migraine ( p = 2.97 × 10 −8 ) by comparing 460 bipolar migraineurs and 914 bipolar patients without migraine (107). Although bipolar disorder shares signs and symptoms with depression, association of this SNP was not observed ( p > 0.05) in the 2013 Psychiatric Genomics Consortium (PGC) MDD GWAS (102) (https://www.med.unc.edu/pgc/files/resultfiles/pgc.mdd.2012-04.zip) and the 2013 International Headache Genetics Consortium (IHGC) migraine GWAS (101).…”

“…In a study using cluster analysis for patients with chronic migraine, patients with high levels of affective temperamental dysregulation showed a higher risk of suicidal behavior [ 24 ]. Recent studies also supported genome wide association between migraine and bipolar disorder, therefore, it is important to identify manageable psychiatric comorbidities for effective treatment and improving life quality among migraineurs [ 25 , 26 ]. However, an association between SCD and comorbid symptoms or pain severity has not yet been investigated with relevant cognitive tests among patients with migraine.…”

“…Among our other findings are loci at 13q13.3, and 9q22.1. The 13q13.3 lead SNP is located within an intron of neurobeachin ( NBEA ), a synaptic scaffolding protein associated with autism (Castermans et al, ) and migraine in bipolar disorder (Jacobsen et al, ). Little is known about spermatogenesis‐associated protein 31C2 ( SPATA31C2 ), the proximal gene at the 9q22.1 locus.…”
