Gregersen, Thomas Damm Als og Guðrið Andorsdóttir Project period: 01/010/18-30/09/21 Total budget: kr. 2.218.982 Grant from the FRC in DKK: kr. 947.019 Project description: Original The demographic history of the isolated population of the Faroe Islands, together with skewed morbidity observed in hereditary diseases, provide strong indications of genetic drift. The population therefore presents great opportunities to discover novel genotype-phenotype relationships, in order to better understand the mechanisms of hereditary diseases. However, in order to take full advantage of this potential, a deeper knowledge of the genetic makeup of the population is paramount. The Genealogy Registry describes familial relationships among the Faroese people. The unprecedented detail of this multigeneration registry makes it a unique resource that is tremendously useful for studying the genetic basis of hereditary disease. In this thesis, I will use next-generation sequencing data in combination with genealogy data to gain insight into the genetic makeup of the Faroese population. Three articles will be published. The first two articles will explore the stratification, diversity and inbreeding within the population. The third article will focus on predicting a complex phenotypic trait, namely stature. The efforts to better understand the genetic makeup of the populaon will improve our ability to predict stature. All relevant data and procedures used to predict stature will be made publicly and readily available, which will enable other researchers to take full advantage of the results of this thesis, and apply these soluons to their own problems. This includes data describing the population stratification, and procedures to use this information, for example how to correct for stratification. Final The main result of this project is a catalog of coding variants in the Faroese population. Additionally, the Multi-Generation Registry was used to describe population structure. Tools and procedures were developed in this process, in order to work with sequencing data as well as genealogical records. We have curated a catalog of coding variants, and are in the process of writing a paper about this catalog. The paper describes the content of this catalog, how it was developed, variant frequencies and population structure. This catalog can be used as a variant reference, and will benefit both researchers and clinicians. Tools and procedures were developed to work with the Multi-Generation Registry. The results include a description of population structure and inbreeding. Additionally, the Multi-Generation Registry was used to select participants for two genetic studies, such that these participants are not closely related. The method used for participant selection was described in a manuscript as well as in a presentation at Vísindavøkan 2020. We have created datasets and developed procedures to work with genetic data in FarGen Phase 1. This work is a foundation for the FarGen project, and the results from this work will benefit researchers working with genetics in the Faroe Islands. The project was intended as a PhD-project, this part has not been completed yet.
