  1. Most estimates are based on prevalence figures. *Carrier rates determined through direct mutation detection are indicated in red. **The LGMD2C carrier rates for the general Romani population of Bulgaria are probably an overestimate since the screening was conducted in a geographical region where the high risk groups are clustered. ***The screening for the G985 mutation in Spain, performed in Gypsy groups residing in different parts of the country, revealed substantial differences between groups.
