deCODE Discovers a Major Risk Factor for Type 2 Diabetes Dependent on Parent of Origin
"We could make this discovery beacause we are in the unique position ofbeing able to distinguish what is inherited from the mother from what isinherited from the father. This we can do because of the large amount of datawe have assembled on the Icelandic population. These data empower us in manyways. For example, using our ability to impute sequence data, we can multiplyby 100 times the amount of information generated by sequencing oneindividual. We can use these tools to discover and integrate rarer variantsinto our tests and scans, identify drug targets for licensing, and put ourknow-how at the disposal of our service customers. We believe that this is animportant advantage for conducting large-scale whole sequence studies overthe next couple of years," said Kari Stefansson, CEO of deCODE.
Because the risk is inherited and varies in this way, the SNP, located onchromsome 11, had never been linked to T2D even though it had been genotypedin large, traditional genome-wide association studies (GWAS). These do notdistinguish between paternally and maternally inherited SNPs. But deCODE cantrack the parental origin of virtually any SNP in the genome of the tens ofthousands of Icelandic participants in the company's gene discovery work. Inthis study, deCODE used its population-wide genealogy database andproprietary statistical tools to determine the parent of origin of a numberof SNPs in some 40,000 Icelandic participants in the company's gene discoveryprograms. Some of these SNPs had previously been associated with differentdiseases and are located near "imprinted" genes - genes in which only thematernally or paternally inherited copy is "switched-on" to encode a protein.Five of these, one each in breast and skin cancer and three in T2D, showedthat the parental origin of the variants affects the risk they confer.
The paper, "Parental origin of sequence variants associated with complexdiseases," is published online at http://www.nature.com, and will appear inthe December 17 print edition.
deCODE is a global leader in analysing and understanding the humangenome. deCODE has identified key variations in the sequence of the genomeconferring increased risk of major public health challenges fromcardiovascular disease to cancer, and employs its gene discovery engine todevelop DNA-based tests to assess individual risk of common diseases; tolicense its tests and intellectual property to partners; and to providecomprehensive, leading- edge contract services to companies and researchinstitutions around the globe. Through its CLIA- and CAP-certified laboratorydeCODE offers DNA-based tests for gauging risk and empowering prevention ofcommon diseases, including deCODE T2(TM) for type 2 diabetes; deCODE AF(TM)for atrial fibrillation and stroke; deCODE MI(TM) for heart attack; deCODEProstateCancer(TM) for prostate cancer; deCODE Glaucoma(TM) for a major typeof glaucoma; and deCODE BreastCancer, for the common forms of breast cancer.Through its pioneering personal genome analysis service deCODEme(TM), deCODEenables individuals to better understand their risk of dozens of commondiseases and to learn about their ancestry and other traits.
