The group has also shown that in humans, genetic variants of the Oprl1 gene are associated with higher risk
of developing the disorder after exposure to trauma.
However, most disease genes discovered in the past decade indicate only an elevated risk, not a certainty,
of developing the disorders with which they are associated, including cancer, diabetes, and heart disease.
This pet health problem affects members of all canine and feline breeds, but members of the following breeds are at increased
risk of developing this disorder: Dachshund, Basset Hound, Shi Tzu, Lhasa Apso, Corgi, Cocker Spaniel, Beagle and Bulldog.
Now, researchers have detailed evidence that a person's risk
of developing the disorder — which results from experiencing traumatic events like rape and war — is inherited.
His team examined 14 people who had been identified as being at «ultra-high risk»
of developing the disorder — they had already seen a doctor about symptoms like paranoia or hallucinations, but hadn't yet had a psychotic episode.
Although it still can not be cured, or even treated very well, several recent studies hint that some treatments — from estrogen to vitamin E to anti-inflammatory drugs — can reduce either the risk
of developing the disorder or its symptoms.
The risk variant mostly highly associated with MS (HLA - DRB1 * 1501) triples the risk
of developing the disorder.
Certain factors such as smoking appear to increase the risk
of developing these disorders.
