==Overview==
There are several possible causes of [[eczema]], majority of which are [[genetic]] in origin. [[Adverse drug effects]] also manifest as [[eczema]].
The [[etiology]] of [[eczema]] is multifactorial and complex. This involves aberrations in [[genetic]] components, [[adverse effect]]s of certain [[medication]]s, and some environmental factors.

*Damage from the [[Enzyme|enzymatic]] activity of [[allergens]] is usually prevented by the body's own [[protease inhibitor]]s, such as, ''[[LEKTI]]'',  produced from the gene ''[[SPINK5]]''.
