MMP3 and disease of the tendon: Despite not finding an association with the FBN2 SNP, this study observed a gene–gene interaction between TNC-MMP3 and a potential tendon regeneration failure phenotype, where high-performance athletes presenting the TNC-rs2104772-A allele in combination with MMP3-rs591058-T had a higher (1.5 and 2.0, respectively) risk of tendinopathy and the occurrence of ≥3 episodes of disease manifestations.
