Population analysis and determination of the ethnic background are necessary in the study of multifactorial diseases: A study using the Dagestan population as a model

Psoriasis, a multifactorial disease with genetic predisposition, has been used as an example to study the role of the ethnic background in multifactorial diseases in the Dagestan population. The individual information card (IIC) is proposed as the main tool for correct collection and processing of information. The results of the study demonstrate that the Dagestan population is a convenient and adequate model population for studying multifactorial diseases, such as psoriasis, and may serve as an object for studying the role of heredity in the etiologies and pathogeneses of this and other multifactorial diseases.
