Audiological findings in 100 USH2 patients

Abstract : Bilateral sensorineural hearing loss (HL), classically described as mild to severe with a typically down-sloping audiometric configuration, is the earliest symptom occurring in Usher syndrome type II (USH2). Audiological findings were analyzed in a total of 100 USH2 patients (92 families) divided into three groups according to the gene involved: 88 USH2A, 10 GPR98 and 2 DFNB31 patients. A fine analysis of audiograms was performed (pure tone average, degree of severity, configuration). The median age of HL diagnosis was 5 years (range 8 months-31 years) although the median age at USH2 diagnosis was 34.5 (range 8-76). Moderate HL was predominant (76%) and a gently down-sloping configuration characterized most audiograms (66%). No statistically significant difference was found between USH2A and GPR98 patients but a tendency was clearly noted for more GPR98 patients to present with severe hearing loss. It is not possible to predict the mutated gene from audiograms.
