Genetic basis of otosclerosis

Abstract

Introduction Otosclerosis is a disorder of the bone labyrinth and stapes resulting in conductive hearing loss. The genetic basis of otosclerosis still remains unknown. We aimed at reporting a comprehensive review of up-to-date knowledge on genetic basis of otosclerosis. Methods Narrative literature review was undertaken to summarize the data about genetics of otosclerosis. Results Genetics of otosclerosis has not been studied extensively and the literature on this topic is scarce. However, knowledge of genetic basis of otosclerosis is recently increasing. We have presented an overview of the knowledge of association of genetic markers with otosclerosis, gained from linkage analyses, candidate-gene studies, and modern high-throughput genomic studies. Conclusion Due to its complex pathophysiology, otosclerosis is not a disease whose genetic base will be easily understood. Multiple omics analysis and bioinformatics will lead to elucidation of genetic basis of otosclerosis. © 2020, Serbia Medical Society. All rights reserved.
