Did you know that a group of zebras is called a dazzle?

In medical school, many doctors are taught the old saying "when you hear hoof beats, think horses, not zebras", which means that doctors should consider the most likely possibility first when thinking of a diagnosis. However, Homocystinuria is very rare (like zebras), so HCU Network America is participating in Rare Disease Day to remind patients, families, and doctors that not all diseases are horses? some are zebras!
