The Hb Lepore trait is found worldwide and may affect people of various races, however the three main kinds of Hb Lepore, usually affects Caucasians of the Southern regions of Central and Eastern Europe.

There are three main kinds of Hb Lepore are named for the areas they were first found in, with various subtypes, the three main kinds are:
