Heritability up to 75%. Filaggrin (FLG) loss-of-function mutations are the strongest known risk factor for eczema.
How Genetic Is Atopic Eczema (Dermatitis)?
Atopic Eczema (Dermatitis) involves complex interactions between multiple genes and environmental factors. Heritability estimates range up to 75%, though no single gene determines outcome on its own.
Key genes associated with Atopic Eczema (Dermatitis): FLG IL4 IL13. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
