Is Eczema Genetic ?
People who suffer from eczema are always pondering whether the eczema is genetic or environmental. The answer is that eczema can be both. Basically eczema is a genetic skin disorder that arises after the many genes responsible for eczema are influenced by certain environmental factors. There are many environmental factors that trigger the irritants that aggravate eczema. |
It goes without saying that genetic factors play an important role in eczema as it many studies have shown that skin disorders usually run in a family. In 2006, scientists made an important breakthrough where they discovered that changes to a gene called filaggrin were associated with eczema. The scientists are now studying whether the changes in the gene also put children at risk of developing milder forms of eczema, which are quite common.
This research clearly shows that a skin barrier defect can cause eczema and other related conditions. The data that was collected shows that almost half of the adult population, who have had severe eczema since childhood, carry mutations to the gene. This means that filaggrin gene causes eczema to appear in childhood, which is more severe, and the disorder may be present even when the child reaches adulthood.
The same group of scientists have conducted further research on filaggrin and have managed to identify further defects in the gene that are present in the general population. On a study conducted on the Irish population, it was found out that 48 percent of the Irish cases, who have moderate to severe eczema, carry one of the five known defects in the filaggrin gene.
