According to the magazine Science , Iceland's "isolated position" and catastrophes that "wiped out large parts of [its] population" have left it with "a remarkably homogenic gene pool." This makes it "relatively easy to track down disease-causing mutations that might form the basis for new tests and therapies."
但令人忧虑的是该数据库公认的"种族一致性"。《科学》杂志认为，冰岛"孤立的地理位置"和"导致该国多数人口死亡"的严重灾难使得现有的基因组合"高度一致"。这大大降低了寻找致病变异的难度，而上述步骤构成了新试验和疗法的基础。"
