The roles of primary cilia in hearing

Summary

Cilia are antenna-like membrane-associated structures which play essential roles during development, and during the normal function of many cells throughout the body. Dysfunction of these organelles can lead to serious illnesses, involving deafness and blindness, as well as life-threatening complications such as kidney and liver disease, diabetes, respiratory problems, and obesity. These so-called “ciliopathies” are usually genetically inherited, and at present there are few, if any cures.

Following collaborations with Phil Beales (Institute of Child Health, UCL) on Bardet-Biedl Syndrome, and with Jan Marshall (Jackson Labs, USA) on Alström Syndrome, we are continuing to work in the field of human ciliary diseases. In collaboration with Colin Johnson (University of Leeds) we more recently characterized the role of the Meckel-Gruber Syndrome protein TMEM67 in the development of the cochlea.

In related public engagement projects I have worked with patient support groups such as Alström Syndrome UK (www.alstrom.org.uk), the Laurence-Moon Bardet-Biedl Society (www.lmbbs.org.uk/), and the Ciliopathy Alliance (www.ciliopathyalliance.org).
