Research Abstract

The gene encoding filaggrin (FLG), whose mutations are well known as a predisposing factor for atopic dermatitis, has a copy number variation. The exon 3 of FLG consists of 10-12 highly homologous repeats. In this study, we analyzed the copy number variation using DNAs taken from 100 patients with atopic dermatitis and determined the frequency of each copy number.
