| Outline of Final Research Achievements |
There are many types of hereditary palmoplantar keratoderma, but causative genes and mechanisms of hyperkeratosis of some types of disease have not been elucidated yet. Recently, our group study hereditary palmoplantar keratoderma extensively. Olmsted syndrome is rare genodermatodes and shows alopecia, periorificial keratoderma and severe itching. The gain-of-function mutation in the gene of TRPV3, which is a Ca2+ channel, is found to cause Olmsted syndrome recently. In this study, we clarify causative mutations in several similar hereditary palmoplantar keratodermas and compare hyperkeratosis mechanisms in Olmsted syndrome and the other palmoplantar keratodermas. Furthermore, we examined model rat of Olmsted syndrome which has the gain-of-function mutation in the gene of TRPV3.
