Although no significant correlations were observed for TFF3 and UPDRS(I), TFF3 and UPDRS(II), TFF3 and UPDRS(IV) or TFF3 and some of burdens of NMSS, there were significant correlations between TFF3 and NMS burdens of mood, attention/memory, as well as gastrointestinal distress in PDD and VPD patients (Table 7). Here, TFF3 is linked to velopharyngeal dysfunction.
