We report a patient with early onset facioscapulohumeral muscular dystrophy type 1 (FSHD1) who was not diagnosed until 48 years of age. She developed progressive facial diplegia from the age of 4-5 years followed by limb muscle weakness. Motor nerve conduction was normal, myopathic changes were seen electromyographically. Creatine kinase activity was mildly increased at the beginning. Muscle biopsy at 8 years suggested a neurogenic pattern, a second biopsy at age 30 was chronic myopathic with fibre calibre variation. The patient lost the ability to walk at age 44. When last seen she had total facial diplegia, no active movements in her limbs, mild kyphoscoliosis and a rigid thoracic spine. Molecular studies revealed a shortened D4Z4 fragment confirming the diagnosis FSHD1. Her family history was unremarkable, suggesting a de novo mutation. This report is to illustrate the evolving phenotype of early onset FSHD1 with predominating facial palsy.
