圣劳伦斯岛的爱斯基摩人在44个离散的基因位点上进行了遗传变异的分型。在2,3‐二磷酸甘油变异酶、肽酶B和嘌呤核苷磷酸化酶位点上观察到三个私人多态性，这可能对未来爱斯基摩人与其他极地人群之间遗传关系的研究有用。遗传距离分析揭示了圣劳伦斯岛爱斯基摩人和其他爱斯基摩人之间的密切关系，爱斯基摩人与美洲印第安人形成了一个独特的群体。圣劳伦斯岛的爱斯基摩人似乎更像亚洲的爱斯基摩人，而不是其他群体。高加索混血儿在这一人群中估计占2%至7%。
The Eskimos of St. Lawrence Island have been typed for genetic variation at 44 discrete genetic loci. Three private polymorphisms, at the 2,3‐diphosphoglycerate mutase, peptidase B, and purine nucleoside phosphorylase loci, have been observed, which may be useful in future studies of genetic relationships between Eskimos and other circumpolar populations. Genetic distance analysis reveals a close relationship between the St. Lawrence Island Eskimos and other Eskimo populations and that the Eskimo populations form a distinct cluster from Amerindian populations. The St. Lawrence Island Eskimos appear to be more similar to Asiatic Eskimos than to other groups. Caucasian admixture in this population is estimated to be between 2 and 7%.
