| Genome-wide association (GWAS) data is highly valuable for biobanks such as Lifelines in identifying disease/trait associations, predicting future disease development and personalized treatment.\\ | Genome-wide association (GWAS) data is highly valuable for biobanks such as Lifelines in identifying disease/trait associations, predicting future disease development and personalized treatment.\\ | ||
| - | To facilitate the generation, analysis and study of genetic data in Lifelines, the UGLI consortium was founded. UGLI brings together many groups and PIs within the UMCG, RUG and beyond that are interested in performing such research with Lifelines data. They have brought the funding together which led to the initial genotyping of a total of 38,030 Lifelines participants, including [[children]], as part of the [[http://glimdna.org|HUGE]] consortium in Rotterdam on the Infinium Global Screening Array® (GSA) MultiEthnic Disease Version 1.0. Together with 15,400 samples already genotyped on the Cytochip ([[GWAS]]), two quality controlled GWAS datasets with a combined sample size of n~50,000 subjects will be made available to members of the UGLI consortium based on specific proposals approved by the UGLI steering committee and by Lifelines.\\ | + | To facilitate the generation, analysis and study of genetic data in Lifelines, the UGLI consortium was founded.

Together with 15,400 samples already genotyped on the CytoSNP array ([[GWAS]]), three quality controlled GWAS datasets with a combined sample size of n~80,000 subjects are available. Genotyping of the remaining Lifelines participants is still ongoing.\\ |
| - | The UGLI consortium is actively raising funding for the genotyping of additional samples. The genotyped additional samples are generally referred to as UGLI2. With additional funding of new UGLI members, the consortium will increase the number of genotyped Lifelines participants. These efforts will make Lifelines a more interesting partner for national and international collaborations as well as with non-academic partners that work on healthy ageing. | + | \\ |
