The [`Silent` effect class](https://github.com/hammerlab/varcode/blob/master/varcode/effects/effect_classes.py#L308) used for synonymous changes return `silent` from `short_description`. I'd recommend conforming to the [HGVS standard now](http://www.hgvs.org/mutnomen/comments001.html), using `p.AminoacidPos=` like `p.T7=`. The fields `aa_ref` and `aa_pos` are already there.
