As I learn more and more about biology I find that many of my physical and physiological traits are a result of genes. For example, yesterday I read an article that says that a single gene causes severe dry skin and asthma, both of which I have. I had always assumed my dry skin was unrelated to my asthma, but it turns out they go hand -in-hand.
Here is the article Link.
“The research, which was led by Professor Irwin McLeod and Dr Frances
Smith, who, through the study, discovered a link between the dry skin
condition ichthyosis vulgaris, eczema and asthma, once the skin cell
gene was identified.
Further research in Europe found that two-thirds of Irish children with
eczema were found to carry one of more filaggrin mutations, while a
study of Scottish children found that the mutation had a direct bearing
on the incidence of those suffering from eczema and asthma
My dry skin is very severe, probably close to diagnosable ichthyosis. I treat it with a variety of methods, Eucerin lotion, aloe gel, and never using bar soap which is extremely drying to my skin. During the summer my skin condition is not as bad. I also need to constantly exfoliate to remove the layers of dead skin that form rapidly, especially on my face.
