“…Lieberthal et al (2015) reported that genetic factors contribute to a portion of tendon and ligament injuries; however, no specific genes were identified. Many recent studies have confirmed that COL1A1 (Bible and Mir, 2015), COL5A1 (Gallamini et al, 2015), COL12A1 (Gaut and Duprez, 2016), and TNC (Cody et al, 2015) are associated with tendon and ligament injuries. COL1A1, COL5A1, COL12A1, and TNC encode collagen I (Salamanna et al, 2015), collagen V (Cody et al, 2015), collagen XII (Harvey et al, 2015), and troponin (Niemi and Majamaa, 2005), a glycoprotein widely present in a large number of tendon tissues, which can withstand high tension and pressure.…”
