This study aimed to investigate whether the TGFBI (rs1442), TGFBR3 (rs1805113 and rs1805117), and MSTN (rs11333758) polymorphisms, either individually or in combination, were associated with susceptibility to muscle injury, anterior cruciate ligament (ACL) rupture, and other injuries. Methods: The study group included 202 physically active Caucasians with reported sport injuries and 133 healthy controls. All the samples were genotyped using real-time polymerase chain reaction (real-time PCR) . Results: The results revealed that (1) the TGFBR3 rs1805117 TC genotype was nominally associated with increased ACL injury risk; (2) the MSTN rs11333758 heterozygotes was more frequent in the one injury group (vs controls) and in the ACL group, whereas [in the multiple vs. one](in the multiple vs. one) comparison the over-dominant model suggested lower odds for heterozygotes; and (3) the TGFBI rs1442 CG genotype was nominally associated with lower odds of fractures, dislocations or sprains. In addition, simultaneous analysis of chosen SNPs revealed interactions between TGFBR3 rs1805117 and rs1805113, with a nominal association of the rs1805113 G allele with increased injury risk, as did rs11333758 and rs1805113, with a potential effect of rs11333758 on injury status. However, haplotype analysis of the TGFBR3 SNPs revealed no significant associations. After Bonferroni correction, none of the associations remained statistically significant. Conclusions: The results suggested that carrying specific TGFBI, TGFBR3, and MSTN genotypes may be potentially associated with susceptibility to musculoskeletal injuries in a physically active Caucasians.  \nKeywords: TGFBI; TGFBR3; MSTN; sport; ACL rupture; muscle injury  \n1. Introduction  \nThe adaptive capacity of skeletal muscle and tendons to changing external factors, such as the volume and intensity of exercise, as well as previous injuries and other physiological conditions, is a key element in determining an individual’s overall mobility, athletic ability, and health. The close anatomical connection between musculoskeletal structures and the shared microcirculation and interstitial fluid suggests efficient communication between these tissues mediated by activated transforming growth factor-beta (TGF-β) family members [1] . This family consists of more than 50 molecules that are structurally  \nrelated, namely, numerous peptide growth and differentiation factors, including activins, bone morphogenetic proteins (BMPs), growth and differentiation factors (GDFs), and three isoforms, namely, TGF-β 1–3. Among them, GDF8, also known as myostatin (MSTN), is a negative regulator of skeletal muscle growth and development [2,3] .  \nBiological processes under the regulation of TGF-β, specifically myoblast and fibroblast cell survival, growth, differentiation","cbCairqkK6G7KMch","https://ap.wps.com/l/cbCairqkK6G7KMch","pdf",1059478,"English","# Abstract\n# 1.
