Study of Genetic Mutations and Their Association With the Development of Atopic Dermatitis and Other Skin Diseases

Abstract

The purpose of this study was to identify the heterogeneity of atopic dermatitis and to identify key genetic factors. This can lead to new approaches and personalized treatment strategies. I conducted a literature review of three scientific publication platforms (i.e., PubMed, Cochrane Library, Scopus) for records published between July 2011 and July 2023 using key words related to the genetics of atopic dermatitis. The high heritability and genetic pleiotropia of atopic dermatitis emphasize the importance of its genetic predisposition and interaction with concomitant diseases. The study also shows the role of various genes associated with immunity and inflammatory reactions, as well as the high heritability of atopic dermatitis, particularly among twins. Genetic mutations, specifically polymorphisms of genes encoding immune factors and inflammatory responses, determine an individual’s predisposition to atopic dermatitis. Research findings also point to genetic aspects associated with other skin conditions such as psoriasis and vitiligo, confirming the existence of common genetic mechanisms between these diseases. Specifically, polymorphisms of the filaggrin gene have been found to be key genetic determinants of atopic dermatitis. I analyzed the genetic basis of atopic dermatitis, emphasizing the importance of genetic determinants and their interaction with the immune system and extracellular matrix. This study contributes to the understanding of the mechanisms of atopic dermatitis and opens new perspectives for individualized treatments.
