Abstract
Specific mutations in the connexin-32 gene that are associated with X-linked Charcot-Marie-Tooth (CMT) disease are disclosed. Methods of diagnosing X-linked CMT disease are also disclosed. Methods include hybridization analysis, such as Southern or Northern analysis, which use hybridization of mutant connexin-32 nucleic acid probes to connexin-32 genes; direct mutation analysis by restriction digest; sequencing of the connexin-32 gene; hybridization of an allele-specific oligonucleotide with amplified genomic DNA; or identification of mutant connexin-32 proteins. Mutant connexin-32 nucleic acid probes are also disclosed. The mutant connexin-32 nucleic acid probes have a mutation in at least one of the following codons: 12, 26, 28, 44, 75, 86, 100, 103, 107, 124, 142, 154, 157, 160, 161, 172, 179, 181, 183, 185, 187, 198, 204, 205, 219, 230 and 235. Mutant connexin-32 nucleic acid probes having more than one of the mutations described above are also described, as are mutant connexin-32 nucleic acid probes having other mutations in addition to at least one mutation as described above. Isolated, mutant connexin-32 proteins encoded by mutant connexin-32 genes, as well as antibodies spe…
