Summary
Genetic factors contribute to tendon and ligament injuries. Variants in the tenascin C (TNC) and collagen V alpha 1 (COL5A1) genes are linked to Achilles tendon issues, offering potential for future injury prevention strategies.
Area of Science:
- Genetics
- Orthopedics
- Sports Medicine
Background:
- Musculoskeletal injuries to tendons and ligaments are common during physical activity.
- Both extrinsic and intrinsic factors contribute to these injuries.
- Emerging research suggests a genetic component to Achilles tendon, rotator cuff, and anterior cruciate ligament injuries.
Purpose of the Study:
- To review current knowledge on genetic associations with tendon and ligament injuries.
- To highlight specific genes implicated in Achilles tendon injuries.
- To underscore the potential for genetic profiling in injury risk assessment.
Main Methods:
- Literature review of studies investigating genetic factors in musculoskeletal injuries.
- Analysis of identified gene variants and their association with specific tendon and ligament injuries.
- Synthesis of findings regarding the roles of tenascin C (TNC) and collagen V alpha 1 (COL5A1) genes.
Main Results:
- Sequence variants in the tenascin C (TNC) gene are associated with Achilles tendinopathies and ruptures.
- A variant in the collagen V alpha 1 (COL5A1) gene is linked to Achilles tendinopathies.
- While specific genes remain unidentified, a genetic predisposition is suggested for rotator cuff and anterior cruciate ligament injuries.
Conclusions:
- The tenascin C (TNC) and collagen V alpha 1 (COL5A1) genes play crucial roles in tendon structure and mechanical response.
- Identifying specific genotypes associated with injury risk could enable proactive prevention strategies.
- Future research may identify genetic markers for rotator cuff and anterior cruciate ligament injuries, aiding personalized risk assessment.

01:43Incomplete Dominance
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.
01:28Disorders of the Skeletal Muscle
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

01:27Principles of Pharmacogenetics: Types of Genetic Variants
The human genome is over 99.9% identical between individuals, yet genetic differences exist at millions of bases. The human genome contains approximately 3 million variant positions per individual, many of which are heterozygous, contributing to genetic diversity and individual traits. Genetic variations include single-nucleotide polymorphisms (SNPs), insertions, deletions, and copy number variations (CNVs).SNPs, the most common variation, involve single-base changes in DNA. These can be...

01:43Sex-linked Disorders
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.
01:28Human Genetics
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
