Re: Genetic roots
Genetic bases in the vast majority of cases are very difficult to establish. If you buy the theory that the causes are psychological then a genetic link is probably nine existent, and early exposure or learned behaviours/reactions are most likely. Even when it appears to run in families genes are unlikely to explain this. The difference is when the cause is physical - adrenal gland dysfunction, higher expression of genes coding for adrenergic receptors, etc. However there might be weight in epigenetic risk factors in some cases. This would count if course only when environmental causes 'switch on' those genes. But as a direct cause, genes just do not explain patterns properly.

Should have pointed out also that genes would really only go so far as to affect 'unexplained panic' - attacks of a physical nature with a general absence of anxious behaviours or psychology.
