Abstract Background: X-linked Charcot-Marie-Tooth type 1 disease has been associated with 280 mutations in the GJB1 [gap junction protein, beta 1, 32kDa (connexin 32, Charcot-Marie-Tooth neuropathy, X-linked)] gene. High-resolution melting analysis with an automated instrument can be used to scan DNA for alterations, but its use in X-linked disorders has not been described. Methods: A 96-well LightScanner for high resolution melting analysis was used to scan amplicons of the GJB1 gene. All mutations reported in this study had been confirmed previously by sequence analysis. DNA samples were amplified with the double-stranded DNA-binding dye LC Green Plus. Melting curves were analyzed as fluorescence difference plots. The shift and curve shapes of melting profiles were used to distinguish controls from patient samples. Results: The method detected each of the 23 mutations used in this study. Eighteen known mutations provided validation of the high-resolution melting method and a further 5 mutations were identified in a blind study. Altered fluorescence difference curves for all the mutations were easily distinguished from the wild-type melting profile. Conclusion: High-resolution melting analysis is a simple, sensitive, and cost-efficient alternative method to scan for gene mutations in the GJB1 gene. The technology has the potential to reduce sequencing burden and would be suitable for mutation screening of exons of large multiexon genes that have been discovered to be associated with Charcot Marie Tooth neuropathy.

Abstract Background: Single base-pair substitution mutations in the gene for coagulation factor VIII, procoagulant component (hemophilia A) (F8) account for approximately 50% of severe cases of hemophilia A (HA), and almost all moderate or mild cases. Because F8 is a large gene, mutation screening using denaturing HPLC or DNA sequencing is time-consuming and expensive. Methods: We evaluated high-resolution melting analysis as an option for screening for F8 gene mutations. The melting curves of amplicons heterozygous for known F8 gene mutations were compared with melting curves of the corresponding normal amplicons to assess whether melting analysis could detect these variants. We examined 2 platforms, the Roche LightCycler 480 (LC480) and the Idaho Technology LightScanner. Results: On both instruments, 18 (90%) of the 20 F8 gene variants we examined were resolved by melting analysis. For the other 2 mutations, the melting curves of the heterozygous amplicons were similar to the corresponding normal amplicons, suggesting these variants may not be detected by this approach in a mutation-scanning screen. Conclusion: High-resolution melting analysis is an appealing technology for F8 gene screening. It is rapid and quickly identifies mutations in the majority of HA patients; samples in which no mutation is detected require further testing by DNA sequencing. The LC480 and LightScanner platforms performed similarly.
