Abstract

Audiograms were traced or additionally performed on 23 Usher's syndrome patients in 10 Dutch multi-affected families, all linked to chromosome 1q (USH2A locus). Serial audiograms, available in 13 patients, were used for a regression analysis of binaural pure tone average on age (follow-up, 9 to 32 years) to test for 'significant progression,' ie, a significant regression coefficient, here called the 'annual threshold increase' (ATI, expressed in decibels per year). A significant ATI (>1 dB/y) was observed in 3 patients. Analysis of variance of ATI demonstrated significant heterogeneity; heating loss was either stable or progressive. This implies a significant clinical heterogeneity. A similar analysis performed on our progressive USH2A cases and 'type III' cases previously reported by others (ATI of 1 to 5 dB/y), some of which were recently linked to chromosome 3q (USH3 locus), failed to show any significant heterogeneity in the progression of hearing loss.
