Detection of CCDC6::RET fusion in PTCs. A Frequency of CCDC6::RET fusion identified by qRT-PCR and ddPCR in 112 PTC samples. B Cross tabulation of the two methods. Chi-square test was used to evaluate effectiveness. C Concentrations of CCDC6::RET fusion positive samples identified by ddPCR. X-axis represented sample ID; Y-axis represented the concentration of RET fusion (copies/uL). D Agarose gel electropherograms of the PCR products of CCDC6::RET fusion positive samples. M, DNA size marker. E Amplification of the low copy RET fusion positive samples by nested PCR. F Representative electropherograms of the CCDC6::RET fusion
