Gender dysphoria (GD) describes individuals for whom the native sex and expressed gender are not coincident and most of them self-identify as transgender women or men. It has been shown that genetic factors play an important role in GD and the presence of specific genetic variants in candidate genes could be correlated. On the other hand, twins studies have estimated its heritability. In this review, we collect and report the available data obtained by different molecular genetic studies.
