Outline of Final Research Achievements

The purpose of this study is to reveal the molecular pathophysiology of gender identity disorder. We conducted whole-genome analysis of 206 female-to-male trans-sexual individuals and 1557 control subjects using Japonica array but failed to identify pathogenesis of gender identity disorder. We intend to perform further research using larger samples.

Academic Significance and Societal Importance of the Research Achievements

病態の手掛かりがない性同一性障害について全ゲノム解析を行ったことは、病態解明に向けた有意義な取り組みであったと考える。今回の解析では病態の解明につながる結果は得られなかったが、この研究を手掛かりにより多くのサンプルでの全ゲノム解析やメタボローム解析を行い、病態解明につなげたい。
