Basic statistical analysis representing CqCV% value of each reference gene. PYCR1, SYMPK, and TBP, respectively showed the lowest CqCV% values in normal tissues (black bars). The least CqCV% values were obtained for SYMPK, PYCR1, and TBP, respectively in PTC tissues (gray bars). The illustration confirmed pseudogene free-SYMPK with the lowest CqCV% value in PTC tissues.
