If there is a common physical deformity with spectrumites, it's that we tend to look younger than our age. There are threads to that effect on here. I haven't read a qualifying medical paper on it, but many on the spectrum believe it to be true.
I've always assumed this wasn't a physical characteristic, but a carryover from a simplicity from our personal style and how we relate to others. The only common feature I've noticed from various examples is facial expression, which probably can be chalked up as part of a flat affect.
