Subjects will be recruited according to our inclusion/exclusion criteria. The investigators employ a multifaceted approach to recruitment, including flyers, community newspaper ads, internet ad postings, and direct recruitment from the Internal Medicine Clinics of Froedtert Memorial Lutheran Hospital/Medical College of Wisconsin which saw approximately 50,000 unique outpatient visits over last year. The electronic health record is leveraged to identify potential subjects by HIPAA guidelines and Medical College of Wisconsin policies. Potential subjects will undergo phenotyping that includes a detailed medical history, anthropomorphic measurements, blood pressure and heart rate measurements, and a blood draw for measurements that include fasting lipids, glucose, and glycosylated hemoglobin, creatinine, and liver function tests. Healthy, non-DM subjects who pass the screening as per the inclusion/exclusion criteria in Table 2 will be enrolled in the study protocol.
