Outline of Final Research Achievements

In order to identify susceptibility genes for chemical-induced vitiligo, we identified at least one gene in genome-wideassociation study in 147 patients with Rhododenol-induced leukoderma (RD) and 112 controls. No loci did not achieve genome-wide significance (P<5x10-8), however, 3 loci achieved suggestive level (P<10-6). Functional investigation revealed that one of the 3 loci, gene A, would be a susceptibility gene for RD with siRNA and expression experiments. Furthermore, the gene A was turned out to not contribute susceptibility to another chemicals.

Academic Significance and Societal Importance of the Research Achievements

2013年7月に社会問題となったRD白斑は、当該化粧品を使用したすべての人に発症しているわけではなく、発症率は使用者の約2%強であった。この発症率はこれまでに報告されてきた他の化学物質誘発性尋常性白斑の発症率とほぼ同様であったことから、化学白斑発症には共通する感受性遺伝子の存在が予想されていたが、本研究により、そのうちの1つを明らかにすることができた。この遺伝子多型を持つ人は、化学物質誘発性尋常性白斑の発症の危険性が高いことを化粧品等を使用前に予想することが可能となった。
