An investigation of DNA sequence variants in genes that regulate collagen fibrillogenesis and predisposition to musculoskeletal soft tissue injuries

Abstract

The aim of this dissertation was to use a case-control genetic study to investigate the association of polymorphisms within the COL5A1, MIR608, COL11A1 and COL11A2, genes with AT and/or ACL injuries in Caucasian populations. These aims were explored in three studies: i) Determine whether the COL5A1 rs71746744 (-/AGGG) and rs1134170 (A/T) polymorphisms and the MIR608 rs4919510 (C/G) polymorphism are associated with ACL rupture risk (Chapter 2). ii) Determine whether the COL11A1 rs3753841 (T/C) and rs1676486 (C/T) polymorphisms and the COL11A2 rs1799907 (A/T) polymorphism are associated with ACL rupture risk. A secondary aim was to determine whether the COL11A1 and COL11A2 polymorphisms interact with COL5A1 rs71746744 (-/AGGG) to modulate ACL rupture risk (Chapter 3). iii) Determine whether the COL11A1 rs3753841 (T/C) and rs1676486 (C/T) and COL11A2 rs1799907 (A/T) polymorphisms are associated with AT risk, and investigate whether these polymorphisms interact with each other, or with the COL5A1 rs71746744 (-/AGGG) polymorphism to modulate the risk of developing AT (Chapter 4).
