Project description:<p>T2D-GENES (Type 2 Diabetes Genetic Exploration by Next-Generation Sequencing in Multi-Ethnic Samples) is a NIDDK-funded international research consortium which seeks to identify genetic variants for type 2 diabetes (T2D) through multiethnic sequencing studies. T2D-GENES Project 1 is a multi-ethnic sequencing study designed to assess whether less common variants play a role in T2D risk and to assess similarities and differences in the distribution of T2D risk variants across ancestry groups. </p> <p>The individuals were obtained from 14 cohorts that are listed in Table 1. The strategy was to perform deep exome sequencing of 12,940 individuals, 6,504 with T2D and 6,436 controls, divided among five ancestry groups: Europeans, East Asians, South Asians, American Hispanics, and African Americans. Sequencing was performed at the Broad Institute using the Agilent v2 capture reagent on Illumina HiSeq machines. Please note that while we summarize the full sample list in publications and below, the Kooperative Gesundheitsforschung in der Region Augsburg (KORA) study does not have a sub study, as it is not consented to be deposited in dbGAP.</p> <p> <p><b>Table 1.</b> T2D-GENES Whole Exome Sequencing Studies</p> <table border="1"> <tr> <th><b>Ancestry</b></th> <th><b>Study</b></th> <th><b>Countries of Origin</b></th> <th><b># Cases</b></th> <th><b># Controls</b></th> </tr> <tr> <td>African American</td> <td>Jackson Heart Study</td> <td>US</td> <td>502</td> <td>527</td> </tr> <tr> <td>African American</td> <td>Wake Forest School of Medicine Study</td> <td>US</td> <td>518</td> <td>532</td> </tr> <tr> <td>East Asian</td> <td>Korea Association Research Project</td> <td>Korea</td> <td>526</td> <td>561</td> </tr> <tr> <td>East Asian</td> <td>Singapore Diabetes Cohort Study; Singapore Prospective Study Program</td> <td>Singapore (Chinese)</td> <td>486</td> <td>592</td> </tr> <tr> <td>European</td> <td>Ashkenazi</td> <td>US, Israel</td> <td>506</td> <td>352</td> </tr> <tr> <td>European</td> <td>Metabolic Syndrome in Men Study (METSIM)</td> <td>Finland</td> <td>484</td> <td>498</td> </tr> <tr> <td>European</td> <td>Finland-United States Investigation of NIDDM Genetics (FUSION) Study</td> <td>Finland</td> <td>472</td> <td>476</td> </tr> <tr> <td>European</td> <td>Kooperative Gesundheitsforschung in der Region Augsburg (KORA)</td> <td>Germany</td> <td>97</td> <td>90</td> </tr> <tr> <td>European</td> <td>UK Type 2 Diabetes Genetics Consortium (UKT2D)</td> <td>UK</td> <td>322</td> <td>320</td> </tr> <tr> <td>European</td> <td>Malmö-Botnia Study</td> <td>Finland, Sweden</td> <td>478</td> <td>443</td> </tr> <tr> <td>Hispanic</td> <td>San Antonio Family Heart Study, San Antonio Family Diabetes/ Gallbladder Study, Veterans Administration Genetic Epidemiology Study, and the Investigation of Nephropathy and Diabetes Study Family Component</td> <td>US</td> <td>272</td> <td>219</td> </tr> <tr> <td>Hispanic</td> <td>Starr County, Texas</td> <td>US</td> <td>749</td> <td>704</td> </tr> <tr> <td>South Asian</td> <td>London Life Sciences Population Study (LOLIPOP)</td> <td>UK (Indian Asian)</td> <td>530</td> <td>538</td> </tr> <td>South Asian</td> <td>Singapore Indian Eye Study</td> <td>Singapore (Indian Asian)</td> <td>563</td> <td>585</td> </table> <p>The London Life Sciences Population Study (LOLIPOP) contributed 530 cases and 538 controls to T2D-GENES Project 1. </p> </p>

Project description:To predict differentially expressed miRNAs between monosomy 3 and disomy 3, and to associate these miRNAs with the clinico-pathological parameters in South Asian Indian population with uveal melanoma (UM). The study consists of six uveal melanoma primary tumour tissues of South Asian-Indian population. These six tumours have been screened for chromosome 3 aberration using Chromogenic in-situ hybridisation (CISH). Thus, sample under the study includes, three each of monosomy 3 and disomy 3. The miRNA profiling was carried out from the tumor sections of formalin-fixed paraffin embedded eyeball samples. miRNA expression profile was obtained in monosomy 3 and disomy 3 samples, analysed by unsupervised analysis (Principal Component Analysis) and supervised analysis (Significance analysis of microarray). The select up-regulated and candidate miRNAs associated with monosomy 3 uveal melanoma tumors were validated further with qRT-PCR (n=86). Thus, this study indicates the role of miRNAs in UM tumor progression and their implication in predetermining the liver metastasis.
