“…In the present study, except for OPRM1, ABCB1, UGT2B7, and P2RX7, we selected other 14 genes known to be involved in systems related to pain perception and modulation based on evidence in the literature. The selected genes have been related to the ion channels (SCN9A, SCN10A, SCN11A, KCNJ6, TRPV1, and CACN A1E) [15][16][17][18][19][20], dopaminergic system (COMT, DRD2) [21,22], purinergic receptor (P2RY12) [23], adrenergic receptor (ADRB1) [24], estrogen receptor (ESR1) [25], serine/ threonine kinase (TAOK3) [26], growth factors (TGFB1) [27], and transcription factor (CREB1) [28]. The aim of the present study was to evaluate the association of common SNPs among aforementioned genes with the inadequate analgesia after single-port VATS.…”
