ABSTRACT
We report a 12-year-old patient with mental impairment and proximal muscle weakness who had marked involvement of the shoulder girdle and facial muscles. CK levels were above 7000 U/l, multiplex PCR dystrophin gene deletion screening was negative. Further molecular studies revealed shortened D4Z4 fragments in the patient and his asymptomatic father, establishing the diagnosis of facioscapulohumeral muscular dystrophy (FSHD). Under the assumption of a second disease mechanism, a muscle biopsy was performed which revealed marked dystrophin deficiency. Eventually, a donor splice site mutation (c.4071+1 G>T) was found by direct sequencing of the dystrophin gene in the patient and his mother and confirmed the diagnosis of Becker's muscular dystrophy along with FSHD.
