Diabetes In Youth

The prevalence of type 2 diabetes in youth has increased substantially, yet the genetic underpinnings remain largely unexplored. To identify genetic variants predisposing to youth-onset type 2 diabetes, we formed ProDiGY, a multi-ethnic collaboration of three studies (TODAY, SEARCH, and T2D-GENES) with 3,006 youth type 2 diabetes cases (mean age 15.1±2.9 y) and 6,061 diabetes-free adult controls (mean age 54.2±12.4 y). After stratifying by principal component-clustered ethnicity, we performed association analyses on ~10 million imputed variants using a generalized linear mixed model incorporating a genetic relationship matrix to account for population structure and adjusting for sex. We identified 7 genome-wide significant loci, including the novel locus rs10992863 in <i>PHF2 </i>(<i>P</i>=3.2´10<sup>-8</sup>, odds ratio [OR]=1.23). Known loci identified in our analysis include rs7903146 in <i>TCF7L2 </i>(<i>P</i>=8.0´10<sup>-20</sup>, OR 1.58), rs72982988 near <i>MC4R </i>(<i>P</i>=4.4´10<sup>-14</sup>, OR=1.53), rs200893788 in <i>CDC123</i> (<i>P</i>=1.1´10<sup>-12</sup>, OR= 1.32), rs2237892 in <i>KCNQ1</i> (<i>P</i>=4.8´10<sup>-11</sup>, OR=1.59), rs937589119 in <i>IGF2BP2</i> (<i>P</i>=3.1´10<sup>-9</sup>, OR=1.34) and rs113748381 in <i>SLC16A11 </i>(<i>P</i>=4.1´10<sup>-8</sup>, OR=1.04). Secondary analysis with 856 diabetes-free youth controls uncovered an additional locus in <i>CPEB2</i> (<i>P</i>=3.2´10<sup>-8</sup>, OR=2.1) and consistent direction of effect for diabetes risk. In conclusion, we identified both known and novel loci in the first genome wide association study (GWAS) of youth-onset type 2 diabetes.

Multiethnic Cohort

Several studies have found associations between higher pancreatic fat content and adverse health outcomes, such as diabetes and the metabolic syndrome, but investigations into the genetic contributions to pancreatic fat are limited.  This genome-wide association study, comprised of 804 participants with MRI-assessed pancreatic fat measurements, was conducted in the ethnically diverse Multiethnic Cohort-Adiposity Phenotype Study (MEC-APS).  Two genetic variants reaching genome-wide significance, rs73449607 on chromosome 13q21.2 (Beta = -0.67, P = 4.50x10 -8 ) and rs7996760 on chromosome 6q14 (Beta = -0.90, P = 4.91x10 -8 ) were associated with percent pancreatic fat on the log scale.  Rs73449607 was most common in the African American population (13%) and rs79967607 was most common in the European American population (6%).  Rs73449607 was also suggestively associated with lower risk of type 2 diabetes (OR = 0.95, 95% CI = 0.89-1.00, P = 0.047) in the Population Architecture Genomics and Epidemiology (PAGE) Study and the DIAbetes Genetics Replication and Meta-analysis (DIAGRAM), which included substantial numbers of non-European ancestry participants (53,102 cases and 193,679 controls).  Rs73449607 is located in an intergenic region between GSX1 and PLUT , and rs79967607 is in intron 1 of EPM2A .  PLUT, a linkRNA, regulates transcription of an adjacent gene, PDX1 , that controls beta-cell function in the mature pancreas, and EPM2A encodes the protein laforin, which plays a critical role in regulating glycogen production.  If validated, these variants may suggest a genetic component for pancreatic fat and a common etiologic link between pancreatic fat and type 2 diabetes.
