Association between MMP16 rs60298754 and clinical phenotypes of Parkinson's disease in southern Chinese

Study objectives: The aim was to investigate the association between MMP16 rs60298754 and symptoms of Parkinson's disease (PD) in southern Chinese.

Methods: Seven hundred forty-five PD patients were recruited in this study. All patients were evaluated by Brief Pain Inventory (BPI), Hamilton anxiety rating scale and Hamilton depression rating scale, 39-item Parkinson's disease Questionnaire (PDQ-39), and MDS-Unified PD Rating Scale (MDS-UPDRS). Symptoms were also recorded.

Results: The difference of BPI and Parkinson's disease sleep scale (PDSS) between two groups was showed (BPI: MMP16 wildtypes: 14.73 ± 14.45; MMP16 carriers: 10.95 ± 10.67, p 0.002; PDSS: MMP16 wildtypes: 117.80 ± 21.45; MMP16 carriers: 108.40 ± 23.95, p < 0.001). The association of apathy, nocturia, and sensitive to light were found (apathy: p 0.001, OR: 0.49, 0.32-0.76; nocturia: p < 0.001, OR: 3.57, 1.90-7.26; sensitive to light: p < 0.001, OR: 3.99, 2.01-7.74).

Conclusions: MMP16 rs60298754 was associated with the presence of apathy, pain, nocturia, and sensitive to light.
