Abstract excerpt

Normal function of the dopaminergic system is necessary for speech fluency. There was evidence that the activities of dopamine transporter (DAT) and dopamine D2 receptor (DRD2) could be altered in people with speech disfluency. This study aims to ascertain the possible correlation between two dopaminergic genes (SLC6A3 and DRD2) and disorder of speech fluency, and to determine the allelic frequencies of the five...
