Extended Data Fig. 7: Population structure of the FinMetSeq dataset, by region.
From: Exome sequencing of Finnish isolates enhances rare-variant association power
Population structure, by region, from a principal component analysis of exome-sequencing variant data (MAF > 1%) for 14,874 unrelated individuals with known parental birthplaces. Colour indicates individuals with both parents born in the same region; grey indicates individuals with different parental birth regions or missing information for one parent. Ctf, Central Finland; COs, Central Ostrobothnia; Kai, Kainuu; Khm, Kanta-Hame; Kyl, Kymenlaakso; Lap, Lapland; Nka, Northern Karelia; NOs, Northern Ostrobothnia; NSv, Northern Savonia; Nfi, individuals born outside Finland and lacking data on parental birthplace; Osb, Ostrobothnia; Phm, Paijat-Hame; Prk, Pirkanmaa; SKa, Southern Karelia; SuK, surrendered Karelia; SOs, Southern Ostrobothnia; SSv, Southern Savonia; Stk, Satakunta; Swf, Southwest Finland; Usm, Uusimaa; X, split parental birthplaces. Large solid circles represent the centre of each region. A map of Finland with regions labelled is supplied for reference.
