Figure 1. DNA sequence chromatograms of GHR exon 10 SNP I526L. PCR products purified by PCR purification kit (Millipore, USA) were used as the DNA template for cycle sequencing. Sequence analysis was performed by BigDye Terminator cycle sequencing in an ABI 3700 DNA sequencer (Applied Biosystems). A is green, C is blue, G is gold, and T is red. The white lines indicate 3 genotypes of the SNP. (a) The heterozygous genotype of AC; (b) the homozygous genotype of CC; and (c) the homozygous genotype of AA.
