  • Patent number: 10689702
    Abstract: The present invention provides a method for assessing the presence and risk of developing type 2 diabetes, cancer of all sites, or cardiovascular disease in a subject by detecting sequence variation in one or more genes such as carboxypeptidase E (CPE) and insulin degradation enzyme (IDE). A kit, array, and device useful for such a method are also provided. In addition, the present invention provides a method for treating type 2 diabetes, cancer of all sites, or cardiovascular disease in patients who have been tested and shown to have the pertinent genetic variations.

  • Patent number: 9518298
    Abstract: The present invention provides a method for assessing the presence and risk of developing type 2 diabetes or cardiovascular disease in a subject by detecting sequence variation in DACH1 (Dachshund homolog 1) gene. A kit and device useful for such a method are also provided. In addition, the present invention provides a method for treating type 2 diabetes or cardiovascular disease in patients who have been tested and shown to have the pertinent genetic variations.

  • Publication number: 20130209447
    Abstract: A method for diagnosing a genetic predisposition in a subject for diseases, disorders or conditions including a diabetic kidney complication such as kidney disease of type 2 diabetes or type 1 diabetes, end stage renal disease (ESRD) due to type 2 diabetes, ESRD due to hypertension in type 2 diabetes, ESRD due to type 1 diabetes; cardiovascular diseases due to type 2 diabetes or type 1 diabetes such as atherosclerotic peripheral vascular disease, hypertension, ischemic cardiomyopathy, and myocardial infarction due to type 2 diabetes or type 1 diabetes; and cerebrovascular accident due to type 2 diabetes. At least one polynucleotide is analyzed to detect a single nucleotide polymorphism (SNP), in which the presence of the single nucleotide polymorphism indicates that the subject is suffering from, at risk for, or suspected of suffering from the diseases, disorders or conditions. Also provided is an array or kit for diagnosing the genetic predisposition.
