Abstract

Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.

Technical Summary

Special contribution relates to the transfer of Professor Steels programme from MRC Institute of Hearing research to the Wellcome Trust Sanger institute. Abstract: Hearing impairment is very common in humans, but it is also a very heterogeneous disorder, with a wide range of causes. For example, there are probably several hundred genes involved in deafness, any one of which can be mutated and cause deafness in an individual. This makes it difficult to study directly in humans. The long-term aim of the work described here is to develop medical treatments for hearing impairment to provide an alternative to the imperfect approaches of amplification and cochlear implantation presently available. Developing new approaches must build upon improved understanding of the causes of hearing impairment and accurate diagnosis. A genetic approach, using hearing-impaired mouse mutants, is adopted to identify the key molecules in the development and function of hearing. As we assemble more of the molecular components, we not only will facilitate the development of generic approaches to treatment, but also establish which are most commonly involved in deafness in the human population. Further work can then focus upon the most common causes of human deafness. In this proposal, I outline plans to build upon the current work of my group to a) investigate the molecular basis of the development of sensory patches in the inner ear, b) investigate the role of key molecules in hair cell development and function, c) use mutants we have studied with a broad range of specific defects to develop diagnostic tools for particular pathologies, and d) screen newly-generated mouse mutants for evidence of hearing and/or balance defects, characterise their pathology, and ask which of the genes involved are associated with deafness in humans.

Title Development of advanced protocols for ABR analysis of auditory function 
Description We have developed a new battery of tests that we use to ask if mouse mutants show any defects in frequency selectivity or temporal processing. 
Type Of Material Model of mechanisms or symptoms - mammalian in vivo 
Provided To Others? No  
Impact Main research is in progress. 
 
Title New deaf mouse mutants 
Description The funding has contributed to the production of many new mouse mutants affecting genes thought to be involved in auditory development or function 
Type Of Material Model of mechanisms or symptoms - mammalian in vivo 
Year Produced 2009 
Provided To Others? Yes  
Impact These new mutants are in the early stages of study, but it looks as if many unexpected genes underlie deafness, while other genes previously thought to be good candidates do not in fact lead to deafness. Around 3% (9/313) of all genes screened so far are associated with hearing impairment, and additional genes are associated with supra-threshold anomalies that we are currently following up. 
 
Title Software and other support for ABR recordings 
Description We supply software that we developed for optimised recording and analysis of Auditory Brainstem Response measurements to assess hearing ability in mice. Also, we supply details of the equipment needed and we host visits by researchers wanting to set the system up in their own lab. 
Type Of Material Improvements to research infrastructure 
Year Produced 2009

Impact The ABR screen using this method has been adopted by the International Mouse Phenotyping Consortium and new data from targeted mouse mutants will emerge to add to our own screening data currently from over 600 new mutant lines, all available on the Sanger Institute Mouse portal
