ICD-10: Q79.6

Ehlers-Danlos syndromes (EDS) are a group of connective tissue disorders characterized by varying degrees of hypermobility, skin elasticity, and tissue fragility. The ICD-10-CM code Q79.6 specifically refers to Ehlers-Danlos syndrome, which encompasses several subtypes, each with distinct clinical features and genetic underpinnings.

Clinical Description

General Characteristics

Ehlers-Danlos syndromes are primarily caused by genetic mutations affecting collagen synthesis and structure, leading to weakened connective tissues. The clinical manifestations can vary widely among individuals, but common features include:

• Joint Hypermobility: Many patients exhibit an increased range of motion in their joints, which can lead to frequent dislocations and joint pain.
• Skin Elasticity: The skin may appear soft, velvety, and highly elastic, often with a tendency to bruise easily.
• Tissue Fragility: Individuals may experience delayed wound healing and a higher risk of developing scars that are thin and fragile.

Subtypes of Ehlers-Danlos Syndrome

There are several recognized subtypes of EDS, each with unique characteristics:

1. Classical EDS: Characterized by skin hyperextensibility, joint hypermobility, and atrophic scarring.
2. Hypermobility EDS: The most common form, primarily involving joint hypermobility and musculoskeletal pain without significant skin involvement.
3. Vascular EDS: Associated with a higher risk of arterial rupture and other vascular complications, this subtype is marked by thin, translucent skin and easy bruising.
4. Kyphoscoliotic EDS: Features include progressive scoliosis and muscle hypotonia, often presenting at birth or early childhood.
5. Arthrochalasia EDS: Characterized by severe joint hypermobility and dislocations, particularly in the hips and shoulders.

Diagnosis

Diagnosis of Ehlers-Danlos syndrome typically involves a combination of clinical evaluation, family history, and genetic testing. The Beighton score is often used to assess joint hypermobility, while skin biopsy may be performed to evaluate collagen structure in certain subtypes.

Prevalence and Impact

The prevalence of Ehlers-Danlos syndromes is estimated to be around 1 in 5,000 to 1 in 20,000 individuals, depending on the subtype. The condition can significantly impact quality of life, leading to chronic pain, fatigue, and psychological challenges due to the chronic nature of the symptoms and the potential for disability.
