Mutations in the Fukutin Related Protein (FKRP) gene cause the condition Limb Girdle Muscular Dystrophy type R9 (LGMDR9) also known as LGMD2i, and the rarer conditions Congenital Muscular Dystrophy (MDC1C), Muscle Eye Brain Disease (MEB) and Walker-Warburg Syndrome (WWS). LGMDR9 is the most common FKRP-related condition, and is especially prevalent in Northern Europe. The aim is to facilitate a questionnaire based research study in order to better characterise and understand the disease globally. By maintaining a global registry this will help identify potential participants eligible for clinical trials in the future.
