A genome-wide CNV association study on panic disorder in a Japanese population.
Family and twin studies have indicated that genetic factors have an important role in panic disorder (PD), whereas its pathogenesis has remained elusive. We conducted a genome-wide copy number variation (CNV) association study to elucidate the involvement of structural variants in the etiology of PD. The participants were 2055 genetically unrelated Japanese people (535 PD cases and 1520 controls). CNVs were detected using Genome-Wide Human SNP array 6.0, determined by Birdsuite and confirmed by PennCNV. They were classified as rare CNVs (found in <1% of the total sample) or common CNVs (found in ≥5%). PLINK was used to perform global burden analysis for rare CNVs and association analysis for common CNVs. The sample yielded 2039 rare CNVs and 79 common CNVs. Significant increases in the rare CNV burden in PD cases were not found. Common duplications in 16p11.2 showed Bonferroni-corrected P-values <0.05. Individuals with PD did not exhibit an increased genome-wide rare CNV burden. Common duplications were associated with PD and found in the pericentromeric region of 16p11.2, which had been reported to be rich in low copy repeats and to harbor developmental disorders, neuropsychiatric disorders and dysmorphic features.
