Background: A review of the studies examining the genetic etiology of panic
disorder shows the familial nature of the disorder and demonstrates that t
he etiology is greatly influenced by genetic factors. Strong evidence for v
ertical transmission in family studies led to molecular genetic studies, of
which association designs appear promising, particularly when based on tra
it markers.
Data Sources: The MEDLINE and PsycLIT databases were searched for all repor
ts published between 1966 and 2000 containing the keywords panic, genetic,
twin, adoption, linkage, association, and QTL.
Conclusion: We conclude that the multifactorial nature of panic disorder re
quires a multidisciplinary approach to gain insight into the determinants o
f the phenotype and the interaction of environmental and genetic factors.
