Abstract

Abstract The aim of this study was to screen 349 patients affected by sensorineural hearing loss (SNHL), mostly from the Campania region (southern Italy), for GJB2 gene mutations and for two deletions of the GJB6 gene (del GJB6 -D13S1830 and del GJB6 -D13S1854). We identified pathogenetic GJB2 mutations in 51 cases (15% of patients). No GJB6 mutation was found. We also examined the audiologic features of the patients for whom we had an etiologic diagnosis, in order to identify correlations between the severity of hearing loss and the type of mutation. Sumario El objetivo de este estudio fue evaluar 349 pacientes afecta-dos de una hipoacusia sensorineural (SNHL), sobre todo de la región de Campania (Italia del sur), buscando muta-ciones en el gen GJB2 y dos deleciones en el gen GJB6 (del GJB6-D13S1830 y del GJB6-13S1854). Identifica-mos mutaciones patogénicas en 51 pacientes (15% de los pacientes). No se encontraron mutaciones del gen GJB6. También examinamos los rasgos audiológicos de aquellos pacientes de quienes teníamos diagnóstico etiológico, para identificar correlaciones entre la severidad de la pérdida audi-tiva y el tipo de mutación.
