A study of patients with [[panic disorder]] or [[social anxiety disorder]], both moderately heritable anxiety disorders, concluded that the [[rs140701]](A) allele was associated with increased risk for both disorders. This SNP was actually part of a tightly linked haplotype A-A-G (for SNPs [[rs3794808]], [[rs140701]] and [[rs4583306]], respectively) that had 1.7x increased risk for [[panic disorder]] (CI: 1.2-2.3).{{PMID|18663369|OA=1
