I didn't know there was a login wall. Try this one: http://www.newscientist.com/article/dn20032-transsexual-differences-caught-on-brain-scan.html#.VEgMHPSTZD0?
The article wasn't mentioning genetics, it was about nMRIs.

The problem with nMRI scans is that if you believe in physicalism, you'd expect every aspect of someone to show up on a sufficiently advanced brain scan. Also, I wonder how many brain regions they tried before finding one that displayed the correct pattern.
What is something you used to believe, preferably something concrete with direct or implied predictions, that you now know was dead wrong. Was your belief rational given what you knew and could know back then, or was it irrational, and why?
Edit: I feel like some of these are getting a bit glib and political. Please try to explain what false assumptions or biases were underlying your beliefs - be introspective - this is LW after all.
