- Diverse trafficking abnormalities of connexin32 mutants causing CMTXSabrina W Yum
Division of Neurology, St Christopher s Hospital For Children, MCP Hahnemann University, Philadelphia, Pennsylvania 19134, USA
Neurobiol Dis 11:43-52. 2002..Thus, many CMTX mutants have trafficking abnormalities, whereas the carboxy-terminus mutants reach the cell membrane and probably cause disease through other mechanisms...
- Dominant connexin26 mutants associated with human hearing loss have trans-dominant effects on connexin30Sabrina W Yum
Division of Neurology, The Children s Hospital of Philadelphia, Department of Neurology, University of Pennsylvania, Philadelphia, PA 19104, USA
Neurobiol Dis 38:226-36. 2010..Furthermore, 8/9 Cx26 mutants inhibited the transfer of neurobiotin or calcein, indicating that these Cx26 mutants have trans-dominant effects on Cx30, an effect that may contribute to the pathogenesis of hearing loss...
