Abstract

Objective: To describe the hearing loss in facioscapulohumeral muscular dystrophy (FSHD) and examine the relationship to genotype. Methods: Medical records of all individuals with FSHD seen at the University of Iowa neuromuscular clinic between July 2006 and July 2012 (n = 59) were reviewed. Eleven had significant hearing loss and no non-FSHD cause. All available audiology records for these individuals were analyzed. The relationship between the FSHD mutation (EcoRI/BlnI fragment size) and hearing loss was evaluated using a logistic regression analysis. Results: In patients with hearing loss, recalled age at onset of facial weakness ranged from birth to 5 years and shoulder weakness was 3 to 15 years. The age at diagnosis of hearing loss ranged from birth to 7 years. Only 2 were identified by newborn hearing screen. Most audiograms demonstrated a bilateral, sloping, high-frequency sensorineural hearing loss. Of the 4 patients with more than 5 years of data, 3 had progression of hearing loss. Logistic regression showed statistically significant negative association between the presence of hearing loss and EcoRI/BlnI fragment size (p = 0.0207). Conclusions: FSHD with a small EcoRI/BlnI fragment is associated with a bilateral, progressive, sloping, high-frequency hearing loss with onset in childhood. Patients with FSHD and small EcoRI/BlnI fragment sizes should have hearing screened, even if the child passed newborn hearing screening.
