Table 1. PCR amplification and denaturing high performance liquid chromatography analysis: primers and conditions
The name of the fragment indicates the exon of the CHM gene amplified (e.g., chm1 for exon 1; two separate fragments chm5.1, and chm5.2 for exon 5). Column temperatures are indicated as astersk if sequence variations were found in the corresponding PCR fragments. Sequence variations were detected in five PCR fragments: chm2, chm5.2, chm6, chm8, and chm13. Optimization of the PCR amplifying fragment chm9 failed probably because of its low GC content (24.5%) and the presence of short tandem repeats within the fragment. (Cycle sequencing of cDNA prepared from a subsequent second sample did not reveal any sequence variation in exon 9 in the samples tested).
