Molecular basis of touch sensation: Researchers identify new function of a well-known gene

A gene known to control lens development in mice and humans is also crucial for the development of neurons responsible for mechanosensory function, as neurobiologists have now discovered. They found that in mice in which they had removed the c-Maf gene in the nerve cells, touch sensation is impaired. This similarly applies to human carriers of a mutant c-Maf gene.
