Insights

Hypermobility is common in rare inherited connective tissue disorders (HDCTs) like Ehlers-Danlos syndrome. Researchers explore if symptomatic hypermobility exists independently of these genetic conditions.

Area of Science:

  • Genetics
  • Rheumatology
  • Rare Diseases

Background:

  • Hypermobility is a shared characteristic of hereditary connective tissue disorders (HDCTs), including Ehlers-Danlos syndrome, Marfan syndrome, and osteogenesis imperfecta.
  • Hypermobility is also frequently observed in the general population, complicating diagnosis.
  • Benign joint hypermobility syndrome shares many features with HDCTs, leading to diagnostic challenges.

Purpose of the Study:

  • To investigate the relationship between symptomatic hypermobility and hereditary connective tissue disorders (HDCTs).
  • To determine if hypermobility can exist independently of diagnosed HDCTs.

Main Methods:

  • Review of existing literature on HDCTs and hypermobility syndromes.
  • Comparative analysis of clinical features and diagnostic criteria for HDCTs and benign joint hypermobility syndrome.

Main Results:

  • Hypermobility is a common feature across various HDCTs.
  • Significant overlap exists between benign joint hypermobility syndrome and HDCTs.
  • The independent existence of hypermobility unrelated to HDCTs remains unclear.

Conclusions:

  • Further research is needed to differentiate between hypermobility as a symptom of HDCTs and as an independent condition.
  • Clarifying the relationship between hypermobility and HDCTs is crucial for accurate diagnosis and management.

Collagens are the Major Structural Proteins of ECM

Three main types of fibers are secreted by fibroblasts: collagen fibers, elastic fibers, and reticular fibers. Collagen fiber is made from fibrous protein subunits linked together to form a long, straight fiber. Collagen fibers, while flexible, have great tensile strength, resist stretching, and give ligaments and tendons their characteristic resilience and strength. These fibers hold connective tissues together, even during the body's movement.

Fibril-associated Collagen01:11

Fibril-associated Collagen

Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...
Matrix Proteoglycans and Glycoproteins01:21

Matrix Proteoglycans and Glycoproteins

Proteoglycans are extensively glycosylated proteins, commonly found in the extracellular matrix, interwoven with collagen fibers. Hyaline cartilage, the most common type of cartilage in the body, consists of short and dispersed collagen fibers associated with large amounts of proteoglycans. These proteoglycans have long negative charges that attract cations, which in turn attract water molecules. This influx of ions and water molecules swells up the proteoglycan like a water-soaked gel that can...
Type IV Collagen of Basal Lamina01:05

Type IV Collagen of Basal Lamina

Type IV collagen is a 400 nm long, network-forming collagen that acts as a barrier between the epithelial and endothelial cells. Type IV collagen  forms the backbone of the basement membrane by scaffolding with laminin, entactin, proteoglycans, and fibronectin. Apart from rendering structural support to the basement membrane, it also helps entail signaling potentials necessary for both pathological and physiological functions.
A type IV collagen molecule has six alpha chains which can exist in...
Introduction to Connective Tissues01:11

Introduction to Connective Tissues

Connective tissues are one of the four main tissue types in humans that are extensively present in the body. They are characterized by cells embedded in an extracellular matrix (ECM) composed of a ground substance and three main types of protein fibers— collagen, elastic, and reticular fibers. The ground substance of connective tissues can range from a watery and jelly-like consistency to mineralized and hard. The wide variety of cells in the connective tissues include fibroblasts, osteocytes,...

Disorders 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...
