Audiological Features and Mapping of a Large Chinese Family with Autosomal Dominant Hereditary Nonsyndromic Hearing Loss
摘要
Abstract
objective To analyze the audiological and hereditary features and to map a DFNA locus of a six-generation Chinese kindred with autosomal dominant nonsyndromic hearing loss. Methods 121 members of this family received the case history inquisition, physical examination, pure-tone audiometry and acoustic immitance measurement. The data of this family were collected. All these data were collected for audiological and hereditary feature analysis.A pedigree diagram was drawn according to the hereditary information. Results The affected members showed postlingual, late-onset, progressive, bilateral moderate to severe sensorineural hearing impairment involving all frequencies. The hearing loss began at the high frequencies and lower frequencies became involved with increasing age, thus causing a flat audiogram.Conclusion This family show autosomal dominant inheritance and high-frequency sensorineural hearing impairment. Through genome-wide linkage analysis with SNP markers, the mutation is identified at 190384723-190669832 zone of chromosome 4.关键词
