The aim of our research is the identification and functional characterization of genes for monogenic and multifactorial skin and hair disorders, with a major focus on disorders of hair loss. Our projects have the long-term aim of systematically understanding the complete physiology of hair growth. The starting point of the projects, which are based on molecular genetic approaches, is to identify new genes on the basis of disease phenotypes. Newly identified genes and insights regarding their function will supply us with fundamental information about the molecular and pathophysiological mechanisms underlying hair loss and hair growth. In recent years, we were able to identify more than 10 novel genes for monogenic forms of hair loss and hair abnormalities, and 3 genes for the hyperpigmentation disorder Dowling-Degos, as well as 14 gene loci for alopecia areata (AA). Recent studies on AA led to interesting drug targets for novel therapeutic approaches for AA.
