What are common features of someone with wolf? Hirschhorn syndrome?

Varies. There are very few "syndromes" with only one appearance, or have a unique characteristic that immediately allows diagnosis at a glance in all cases. Wolf-Hirschhorn Syndrome is so rare, most of us have never heard of it. Glad you asked, so I could find out too!
