Abstract: Methods are described for screening a subject for risk of Charcot-Marie-Tooth Disease Type 2A or for diagnosing Charcot-Marie-Tooth disease or a predisposition for developing Charcot-Marie-Tooth disease in a subject, by detecting the presence or absence of a mutation in the mitofusin gene in a biological sample collected from the subject. Methods are also described for detecting the presence of a genetic polymorphism associated with Charcot-Marie-Tooth Disease Type 2A in a sample of patient nucleic acid, by amplifying a mitofusin gene sequence in the patient nucleic acid to produce an amplification product; and identifying the presence of a Charcot-Marie-Tooth Disease Type 2A associated polymorphism in the amplification product.

Abstract: The present invention provides methods and compositions for screening a subject for Parkinson disease, for increased risk of developing Parkinson disease and/or for an earlier or later age of developing Parkinson disease, comprising detecting the presence of a genetic marker associated with Parkinson disease.

Abstract: The present invention provides methods of identifying a subject having an increased or decreased risk of developing cardiovascular disease, comprising: a) correlating the presence of one or more genetic markers in chromosome 3q13.31 with an increased or decreased risk of developing cardiovascular disease; and b) detecting the one or more genetic markers of step (a) in the subject, thereby identifying the subject as having an increased or decreased risk of developing cardiovascular disease. Also provided are methods of identifying subjects with cardiovascular disease as having a good or poor prognosis, as well as methods of identifying effective treatment regimens for cardiovascular disease, based on correlation with genetic markers in chromosome 3q13.31.

Abstract: The present invention discloses methods of screening a subject for Alzheimer's disease and/or Parkinson's disease comprising detecting the presence or absence of a marker or functional polymorphism associated with a gene linked to Alzheimer's disease and/or Parkinson's disease.

Abstract: GAPDH binds to expanded polyglutamine regions which are found in proteins encoded by genes with CAG repeat domains, which genes cause inherited neurodegenerative disorders and are associated with certain psychiatric disorders. Therapeutic methods are based on inhibiting the binding of GAPDH to expanded polyglutamine regions. A method of screening compounds for the ability to inhibit binding of GAPDH to polyglutamine regions is described.
