ABSTRACT
Hereditary deafness is one of the most common sensory disorders in humans, and exhibits high genetic heterogeneity. At present, the commonly used molecular diagnostic methods include gene chip, Sanger sequencing, targeted enrichment sequencing, and whole-exome sequencing, with diagnosis rates reaching 33.5%-56.67%. However, there are still a considerable number of patients who can not get a timely and definitive molecular diagnosis. Furthermore, considering the economic burden on patients' families and the relatively high cost of whole-exome or whole-genome sequencing, it is vital to provide stepwise strategies combining multiple detection methods according to the phenotypes of patients. In this review, we evaluate and discuss the utility of molecular diagnosis and the application of stepwise testing strategies in hereditary deafness to provide reference for the selection of diagnostic strategies.
