Illumina Unveils the First Industry-Hosted Controls Database for Genetic Research

June 11, 2007

New Open-Access Database Boasts More Than 6,000 Control Samples

SAN DIEGO--(BUSINESS WIRE)--June 11, 2007--Illumina, Inc.,(Nasdaq:ILMN) announced today the launch of iControlDB, the firstindustry-hosted genotyping control repository available for immediateuse by researchers conducting case-control whole-genome associationstudies. Case-control studies compare groups of patients who alreadyhave a disease (case) with a group of patients without the disease(control) to identify risk factors that may contribute to a medicalcondition. Located at www.illumina.com/iControlDB, iControlDB providesa cost-efficient and quicker way for investigators to obtain controlsamples, allowing them to focus resources on genotyping diseasesamples. Combined with the database of Genotype and Phenotype (dbGaP),the scientific community can now access nearly 10,000 control samplesthat have been donated by researchers using Illumina's technology forsingle-nucleotide polymorphism (SNP) genotyping.

Peter Gregersen, M.D., is Director of the Robert S. Boas Centerfor Genomics and Human Genetics at the Feinstein Institute for MedicalResearch, and has contributed more than 2,300 samples to iControlDB.Says Gregersen, "I think it is a unique milestone to have this manycontrol samples freely available for case-control whole-genomeassociation studies. In fact, it is a major gift to the scientificcommunity, allowing many investigators to more quickly and efficientlyconduct genetic mapping of human diseases, at a substantially reducedcost."

Leading genomics institutes, including the Robert S. Boas Centerfor Genomics and Human Genetics at the Feinstein Institute for MedicalResearch and The Children's Hospital of Philadelphia are the first todonate, in total, more than 6,000 control samples to the database. Inaddition to controls deposited from the International HapMap Project,the database contains samples from Caucasian, African, AfricanAmerican, African-American Mixed Descent, Chinese, Japanese, Korean,Native Hawaiian/Pacific Islander, Hispanic, Hispanic-Mixed Descent,Indian, and Vietnamese populations.

Researchers interested in obtaining data from iControlDB can do sovia a downloadable software tool found at www.illumina.com/iControlDB. For investigators wanting to upload their control samples, they can dothis in concordance with Health Insurance Portability andAccountability Act (HIPAA) guidelines, and with valid approvaldocumentation, such as an institutional review board (IRB) approval,using Illumina's BeadStudio Data Analysis Software, version 3.1.

"This database will benefit the research community at large byproviding investigators with an extensive set of control samples tovalidate their genetic studies," said Hakon Hakonarson, M.D., Ph.D.,Director of the Center for Applied Genomics at The Children's Hospitalof Philadelphia, who supplied 4,000 control samples to the database."Having this tool available allows researchers to significantly reduceboth time and expenses in their genotyping studies. We hope this willfacilitate collaborative interactions and advance our goal of buildingscientific foundations for developing successful treatments forchildhood diseases."

All data uploaded to iControlDB are subject to Illumina's rigorousquality control process. To date, control samples uploaded to thisdatabase have an average call rate of 99.6 percent. By the end of2007, samples in iControlDB are expected to reach more than 20,000.

"We created iControlDB because we want researchers to haveimmediate access to data that would otherwise be more time-consuming,cumbersome, and costly to obtain. We estimate that this database willprovide at least a 50 percent cost savings, in addition to nearlyhalving the time necessary for processing samples," said CarstenRosenow, Ph.D., DNA Analysis Senior Marketing Manager at Illumina."The overall value for customers is that we are helping them findresults faster, without compromising data quality, speeding their wayto gene variation discovery."

About iControlDB

Genetic case-control association studies are becoming morewidespread in the scientific community. As part of an ongoinginitiative, Illumina has identified a need by the life sciencecommunity to access genotypic data from individuals that can be usedas controls in case-control association studies. It is Illumina'sintent to provide an online repository for such data accessible to thescientific community in order to further scientific progress usingthese resources, subject to appropriate terms and conditions.
