Effect of gene polymorphisms on the mechanical properties of human tendon structures.

ABSTRACT: Recent studies showed that polymorphisms in alpha 1 chains of types I (COL1A1) and V (COL5A1) collagen, growth and differentiation factor 5 (GDF5), and matrix metalloproteinase 3 (MMP3) genes were associated with injuries in tendons and ligaments (e.g., September et al. (Br J Sports Med 43: 357-365 2009)). In the present study, we aimed to investigate the effects of injury-associated polymorphisms within these four genes on the mechanical properties of human tendon structures in vivo. One hundred Japanese males participated in this experiment. The mechanical properties of tendon structures in knee extensors and plantar flexors were measured using ultrasonography. All subjects were genotyped for COL1A1 rs1800012, COL5A1 rs12722, GDF5 rs143383, and MMP3 rs679620 single nucleotide polymorphis
