PRPP syn·the·tase (sin'the-tās),

The four mutations identified in the PRPS1 gene cause a decrease in the production of the PRPP synthetase 1 protein that results in defects in sensory cells (called hair cells) in the inner ear, and eventually leads to progressive deafness.
"Our findings emphasize the body's need for tight regulation of PRPP synthetase 1 since a drop in activity can lead to deafness."
