A person's genes can show if they are predisposed to be transgender, new research has suggested.
The study, titled "A genetic link between gender dysphoria and sex hormone signalling," was published in the peer-reviewed The Journal of Clinical Endocrinology & Metabolism on September 21.
It found that trans people's sex hormone genes tend to look different to those of cisgender people and produce different physiological results.

This research adds to several previous studies that indicate that being transgender is a matter of a person's biology—such as the University of São Paulo's Medical School research, released last year, which found that the brains of trans and cis adults are significantly different.
It discovered that a region of the brain called the insula had a distinct volume, depending on whether it was in the brain of a trans or cis subject.
This latest research, which looked at 380 trans women and 344 cis men in Australia and the US, has revealed a significant link between genes for sex hormones and whether someone is a cis man or a trans woman.
While the make-up of the several specific genes analysed by researchers does not guarantee that the subject will or won't be trans, it makes it much more likely."
