Mice harbouring an oculodentodigital dysplasia-linked Cx43 G60S mutation have severe hearing loss.

Abstract excerpt

Given the importance of connexin43 (Cx43, encoded by GJA1) function in the central nervous system and sensory organ processing, we proposed that it would also be crucial in auditory function. To that end, hearing was examined in two mouse models of oculodentodigital dysplasia that globally express GJA1 mutations resulting in mild or severe loss of Cx43 function. Although Cx43I130T/+ mutant mice, with ∼50% Cx43...
