- Craniofacial anomalies
- Postnatal growth restriction
- Kyphoscoliotic Ehlers-Danlos Syndrome (PLOD1, Autosomal Recessive)
- Congenital muscle hypotonia
- Kyphoscoliotic Ehlers-Danlos Syndrome with Myopathy and neurosensory Hearing Loss (FKBP14, Autosomal Recessive)
- Congenital muscle hypotonia
- Muscle Atrophy
- Congenital Hearing Deficit
IV. Exam: Classic Ehlers-Danlos Syndrome
- Skin
- Soft dough-like feel
- Hyperextensible
- Fragile (splits easily with minor Trauma)
- Joint surfaces (e.g. knees, elbows)
- Trauma prone regions (e.g. chin, shins)
- Poor Wound Healing (with scar Stretching)
- Easy Bruising
- Joints
- Neurologic
- Hypotonia
- Delayed motor development
- Muscle Fatigue
- Myalgias
- Cardiovascular
- Mitral Valve Prolapse (uncommon, and typically benign)
- Aortic root dilation (uncommon, and typically static)
V. Diagnosis: Classic Ehlers-Danlos Syndrome
- Major Criteria
- Skin hyperextensibility AND
- Atrophic Scarring AND
- Generalized joint hypermobility OR 3 minor criteria
- Minor Criteria (3 required if absence of Generalized joint hypermobility)
- Easy Bruising
- Soft doughy skin
- Skin fragility or Traumatic splitting
- Molluscoid pseudotumors
- Elevated lesions over scarred pressure points (e.g. elbows, knees)
- Subcutaneous spheroids
- Small round hard densities mobile and palpable within the skin of the forarm or shin
- Hernia
- Epicanthal Folds
- Joint hypermobility complications (sprains, dislocations, flexible flat foot)
- First degree relative with Ehlers-Danlos Syndrome diagnostic criteria met
-
Genetic Confirmation (panel)
- COL5A1
- COL5A2
- COL1A1 (less common)
VI. Differential Diagnosis
- See Hypermobility syndrome
- See types as above
VII. Imaging
-
Echocardiogram
- Indicated for aortic dilation or Mitral Valve Prolapse
- Repeat yearly, if anomaly present
VIII. Management
-
General
- Avoid Aspirin
- Avoid Contact Sports
- Hypotonia or delayed motor development
- Physiotherapy
- Pool Exercise and other non-weight bearing activities
- Joint Pain
-
Skin Wounds
- Close with two layers, and generous deep Sutures to reduce skin tension
- Skin protection (knee pads, shin pads or stockings)
- Bruising
- Bleeding complications
- Consider DDAVP
IX. Prevention: Genetic Counseling
- At least 50% of Ehlers-Danlos Syndrome patients have an affected parent (remainder are de novo)
- Known parent with Classic Ehlers-Danlos Syndrome (EDS) has a 50% chance of a child with EDS

| Definition (MSH) | A heterogeneous group of autosomally inherited COLLAGEN DISEASES caused by defects in the synthesis or structure of FIBRILLAR COLLAGEN. There are numerous subtypes: classical, hypermobility, vascular, and others. Common clinical features include hyperextensible skin and joints, skin fragility and reduced wound healing capability. |

| Definition (MEDLINEPLUS) |
Ehlers-Danlos syndrome (EDS) is a group of inherited disorders that weaken connective tissues. Connective tissues are proteins that support skin, bones, blood vessels, and other organs. EDS usually affects your skin, joints and blood vessel walls. Symptoms include
There are several types of EDS. They can range from mild to life-threatening. About 1 in 5,000 people has EDS. There is no cure. Treatment involves managing symptoms, often with medicines and physical therapy. It also includes learning how to protect your joints and prevent injuries. |

| Definition (CSP) | group of inherited disorders of the connective tissue; major manifestations include hyperextensible skin and joints, easy bruisability, friability of tissues with bleeding and poor wound healing, calcified subcutaneous spheroids, and pseudotumors. |
