What Causes Eczema?

Pubmed has an article from Switzerland about the genetics involved in eczema –

Atopic eczema (AE) is a multifactorial skin disease caused by a variety of factors such as genetic conditions, alterated skin structure, immunologic deviations and environmental factors, among others.

Recently, it was demonstrated that Filaggrin (=filament-aggregating protein, FL) is a major gene for atopic eczema.

The BBC covered an interesting study into cat exposure sparking eczema in babies.

Scientists found having the mutant FLG gene increased the risk of eczema in a baby’s first year twofold, but adding exposure to a cat quadrupled that risk.

Another Pubmed article, from Royal Victoria Infirmary, notes

The discovery that null mutations in the filaggrin gene (FLG) are associated with atopic eczema represents the single most significant breakthrough in understanding the genetic basis of this complex disorder.

It’s very exciting to know that doctors have pinned what causes eczema, even if we don’t quite know what to do with that knowledge yet.
