This is a GWAS pilot study that aims to identified possible candidate genes associate to obesity by exploring single nucleotide polymorphism (SNP) in a small group of obese , metabolically healthy white adults, matched with lean, white adults , metabolically healthy. The investigators hypothesize that the careful phenotyping of the subject sand matching with increase the power to find SNP significantly associate with obesity (as defined by BMI).
Between 60%-70% of the risk of obesity appears to be heritable. Unfortunately, the exact genes involved have been difficult to identify. New technologies now exist to help researchers discover obesity susceptibility genes. One of these technologies is the Affymetrix Genome-Wide Human SNP (single nucleotide polymorphism) Array 6.0 chips. SNPs are individual base pair differences in genes of different individuals, and they are the main source of human genetic diversity. The "chips" are thumbnail-size silicon surfaces that contain copies of hundreds of thousands of SNPs of the human genome (in this case around 900,000). SNP chips allow researchers to screen thousands of genes in a single experiment and compare genes of subjects with a particular disease or condition with unaffected control subjects. The investigators study utilizes SNP chips to compare the genetic profiles of obese subjects (N = 20, body mass index > 35 kg/m2) without common obesity-related co-morbidities such as diabetes mellitus or hypertension with well matched, lean controls (N = 20, body mass index 18-25 kg/m2). This is a pilot study intended to explore the following: 1) possible associations between obesity and previously unidentified obesity susceptibility genes; 2) associations between known obesity genes and obesity risk in subjects without obesity-related metabolic co-morbidities; and 3) how well our genetic data conform to other studies in similar populations as a way of assessing if the investigators have identified a representative cohort of obese subjects.
