Mutations in the GJB6 gene encodinp connexin 30 (Cx30) can cause dominant f
orms of nonsyndromic deafness. By studying immunohistochemical localization
of Cx30 in the mouse cochlea at different ages from 0 to 30 days after bir
th, we found that the expression of Cx30 is nearly the same as that of Cx26
. These findings suggest that as weil as Cs26. Cx30 may also contribute to
the generation and maturation of endocochlear potential. (C) 2001 Elsevier
