Pax3 function is required specifically for inner ear structures with melanogenic fates.

Abstract excerpt

Pax3 mutations result in malformed inner ears in Splotch mutant mice and hearing loss in humans with Waardenburg's syndrome type I. In the inner ear, Pax3 is thought to be involved mainly in the development of neural crest. However, recent studies have shown that Pax3-expressing cells contribute extensively to multiple inner ear structures, some of which were considered to be derived from the otic epithelium. To...
