1. A method of determining the level of susceptibility of a subject to an environmental toxin capable of detoxification by a glutathione S-transferase comprising:
- a. determining a first amount of one or more glutathione S-transferases present in a biological sample from the subject;
b. contacting the biological sample with the environmental toxin;
c. determining a second amount of one or more glutathione S-transferases present in the sample;
wherein the second amount of one or more glutathione S-transferases being lower than or similar to the first amount of one or more glutathione S-transferases indicates the subject having a higher level of susceptibility than a subject having the second amount of one or more glutathione S-transferases higher than the first amount of one or more glutathione S-transferases, and wherein the second amount of one or more glutathione S-transferases being higher than the first amount of one or more glutathione S-transferases indicates the subject having a lower level of susceptibility than a subject having a second amount of one or more glutathione S-transferases lower than or similar to the first amount of one or more glutathione S-transferases.

Abstract
The present invention relates to the identification of a gene encoding the protein glutathione S-transferase pi2 as being correlated with the susceptibility to neurotoxicity and concomitantly the risk to develop Parkinson'"'"'s disease. Based on this correlation, various methods are disclosed, including determining the amount of the one or more glutathione S-transferase present in a biological sample in response to an environmental toxin, to assess the risk to develop Parkinson'"'"'s disease.

16. A method of determining risk of developing Parkinson'"'"'s disease in a human comprising:
-
a. determining a first amount of one or more glutathione S-transferases present in a biological sample from the subject;
b. contacting the biological sample with the environmental toxin;
c. determining a second amount of one or more glutathione S-transferases present in the sample;
wherein the second amount of one or more glutathione S-transferases being lower than or similar to the first amount of one or more glutathione S-transferases indicates the subject having a higher level of risk of developing Parkinson'"'"'s disease than a subject having the second amount of one or more glutathione S-transferases higher than the first amount of one or more glutathione S-transferases, and wherein the second amount of one or more glutathione S-transferases being higher than the first amount of one or more glutathione S-transferases indicates the subject having a lower level of risk of developing Parkinson'"'"'s disease than a subject having a second amount of the one or more glutathione S-transferases lower than or similar to the first amount of the one or more glutathione S-transferases. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A method to determine genetic susceptibility to an environmental toxin involving contacting a biological sample from a subject with a composition consisting essentially of one or more labeled probes each of which binds selectively to a region on mouse chromosome 1, from D1Mit113 to D1Mit293 under conditions in which one or more labeled probes form stable hybridization complexes with DNA in the region of mouse chromosome I from D1Mit113 to D1Mit293 and detecting the hybridization complex, wherein said hybridization complex is indicative of a genetic susceptibility to an environmental toxin.
