No, no one has been permitted to do this, as far as I know. To paraphrase Dr. Potter on the issue (*very* loosely because he said this quite a while ago), the docs do not know what to look for in the PGD analysis to prevent autism, so they don't consider GS as an answer to ASD risk. In his defense, I will point out that saying you're doing GS for ASD sounds like a weak argument in comparison to people using it for hemophilia or other disorders than actually, really, truly can be averted with the right PGD screening of embryos.
For ASD, it is risk reduction, not true prevention, and it is hard to know (and seriously debated among researchers) how much risk is being reduced by adding a second X-chromsome. For example, Prof. S. Baron-Cohen of the UK's Cambridge argues that female ASD looks a bit different (namely, the deficits are less verbal and a lower rate of comorbid Sensory Processing Disorders) and is thus missed more often in girls, especially at higher IQs. The boy:girl ratio is only 3:2 in IQs under 80-ish (I can't recall the exact cutoff) but 9:1 above 120. He thinks smarter girls are better at hiding their problems, how they're not "getting" social cues and meanings. I know a woman with a little girl Aspie who would probably snort at the idea that having a girl means you can relax on the ASD fears.
Anyway, I understand their points, but still think it's a bit of a callous response to families with one or more special-needs boys with a disorder that, as best we know, is more prevalent in males than females. As I explained recently to a callous OB who was completely shocked by (and aghast at) the idea that people would go to all the trouble and expense of GS IVF/PGD for ASD risk reduction, hey, lady, it's the only tool we have. Blunt, uncertain, but it's the only tool in the toolbox currently.
It can't hurt to ask, explaining your circumstances. You might just find the right sympathetic RE who actually knows something about ASD and why you'd want GS to grab at every bit of risk reduction you could get. (I do believe they exist.) But do know that in places where GS is banned, their hands might be tied by strict rules for which disorders can be covered with GS.
