Functional and genetic analysis of PHF11, a new gene associated with atopic dermatitis and asthma

Funded Activity Summary

Atopic dermatitis, or eczema, is an increasingly common severe allergic condition affecting the skin that afflicts up to 30% of all Australian children. Eczema has significant financial impact on families as well on the health and well being of the affected child. The majority of asthmatics are also allergic, explaining why many children who suffer from eczema often go on to develop asthma as well. A familial history of asthma or eczema is an important risk factors for a child developing the disorder, meaning that allergy is to a large extent determined by the genes we inherit from our parents. Our genes consist of four different building blocks, called nucleotides, which are identified by four letters: A, G, C and T. Each gene has a specific spelling of these four letters, although between any two people there will invariably be small single letter differences in the way a gene is spelt. Normally, these differences have no effect. In an allergic individual, however, these differences do have an effect. Identifying differences in the way a gene is spelt and why this should lead to eczema or asthma is a major research goal. In the past several years a number of genes have been identified that play an important role in allergy and we have recently identified a spelling difference in a new gene that we believe is important in the allergic response of eczema and asthma. At the moment, we can only guess how this gene might work. We know it is expressed in cells of our immune system that are important in allergy. We also suspect it might be an on or off switch for other genes important for allergy. This project will test these ideas and show how differences in the way this gene is spelt lead to differences in how this gene works. This will be important in adding another piece to the puzzle of how genes control allergy and could lead to better and earlier treatment of these disorders with improved health for affected children as well as adults.
