Mitochondrial complex I mutations in Parkinson's disease & aging

Abstract

The present invention provides methods for diagnosing and treating Parkinson's disease based on mitochondrial mutations. The present invention also provides methods for diagnosing and treating other diseases and disorders based on mitochondrial mutations.

1 . A method of diagnosing if a human subject has or will develop Parkinson's Disease, comprising
 determining the presence or absence in the subject of a heteroplasmic, amino acid changing mutation in a region of the mitochondrial ND5 gene,   wherein the region comprises codons 124-148,   wherein the presence of the heteroplasmic, amino acid mutation at one or more of codons 124-148 of the mitochondrial ND5 gene indicates that the human subject has or will develop Parkinson's Disease.   
     
     
         2 . (canceled) 
     
     
         3 . The method of  claim 1 , wherein the region comprises codons 130-148. 
     
     
         4 . The method of  claim 3 , wherein the region comprises codons 136-148 
     
     
         5 . The method of  claim 1 , wherein the region comprises codon 145. 
     
     
         6 . The method of  claim 1 , wherein the heteroplasmic mutation involves at least one of codons 124, 130, 133, 134, 136, 138, 141, 142, 143, 145, and 148. 
     
     
         7 . The method of  claim 1 , wherein the heteroplasmic mutation comprises at least one of the following codon mutations:
 124, F-L   130, I-L   133, T-A   134, A-G   136, N-Y   136, N-S   136, N-D   138, F-S   141, F-S   143, G-A   145, E-D   145, E-G   145, E-V   145, E-ter   148, G-W or   148, G-ter.   
     
     
         8 . The method of  claim 1 , wherein the method confirms a clinical diagnosis of Parkinson's Disease. 
     
     
         9 - 15 . (canceled) 
     
     
         16 . A method of diagnosing if a human subject has Parkinson's Disease, comprising
 determining the presence or absence in the subject of a heteroplasmic, amino acid changing mutation in a region of the mitochondrial ND5 gene,   wherein the region comprises codons 124-148,   wherein the presence of a heteroplasmic, amino acid changing mutation at one or more of codons 124-148 of the mitochondrial ND5 gene indicates that the human subject has Parkinson's Disease.
