Junctional Epidermolysis Bullosa

Junctional Epidermolysis Bullosa (JEB) is a rare genetic skin disorder that causes painful blistering and skin fragility due to a defect in proteins that hold the layers of the skin together. In this article, we’ll break down the condition into simple language, making it easy to understand for everyone.

Types of Junctional Epidermolysis Bullosa

Junctional Epidermolysis Bullosa has several subtypes, which are:

1. Herlitz JEB: This is the most severe form of JEB. Babies born with this type often have blistering all over their bodies and face a high risk of complications.
2. Non-Herlitz JEB: This is a less severe form. Blisters are still present but are generally less severe, and it tends to appear later in life.

Causes of Junctional Epidermolysis Bullosa

JEB is caused by genetic mutations that affect proteins essential for skin integrity. There can be many different genetic changes leading to JEB, but the main cause is inheriting faulty genes from one or both parents.

20 possible genetic mutations that can cause JEB are:

1. COL17A1 gene mutation
2. LAMB3 gene mutation
3. LAMA3 gene mutation
4. LAMC2 gene mutation
5. ITGA6 gene mutation
6. ITGB4 gene mutation
7. CD151 gene mutation
8. DST gene mutation
9. EXPH5 gene mutation
10. ITGB4 gene mutation
11. JUP gene mutation
12. KRT5 gene mutation
13. KRT14 gene mutation
14. LAMC2 gene mutation
15. LAMA3 gene mutation
16. LAMB3 gene mutation
17. PKP1 gene mutation
18. PLEC gene mutation
19. COL17A1 gene mutation
20. TGM5 gene mutation

Symptoms of Junctional Epidermolysis Bullosa

JEB manifests itself through various symptoms, including:

1. Blisters: The hallmark of JEB is painful blisters on the skin, often caused by minor friction or trauma.
2. Raw, Oozing Skin: After blisters break, the skin becomes raw and can ooze fluid.
3. Scarring: Repeated blistering can lead to scarring and deformities.
4. Mouth and Throat Blisters: In severe cases, blisters can form inside the mouth, making eating and swallowing difficult.
5. Nail Changes: Nails may be brittle and easily damaged.
6. Hair Loss: Hair may be fragile and prone to falling out.
7. Difficulty Swallowing: Blisters can affect the lining of the throat, leading to difficulty swallowing.
8. Tooth Decay: Mouth blisters may lead to tooth decay due to poor oral hygiene.
9. Anemia: Chronic inflammation and poor nutrition can lead to anemia.
10. Difficulty Breathing: Severe cases may affect the lining of the airways, causing breathing difficulties.
11. Vision Problems: In some subtypes, blisters can form on the cornea, leading to vision issues.
12. Gastrointestinal Issues: Blisters in the digestive tract can cause pain and complications.
13. Joint Contractures: Long-term blistering can lead to joint problems.
14. Growth Delay: Children with JEB may have delayed growth.
15. Infection Risk: Open blisters increase the risk of infections.
16. Heat Intolerance: The skin may be sensitive to heat.
17. Difficulty Urinating: In some cases, blisters may affect the genital area, leading to pain during urination.
18. Thickened Skin: The skin can become thickened and rough over time.
19. Esophageal Strictures: Severe mouth and throat blisters can lead to esophageal strictures.
20. Teeth Discoloration: Mouth blisters may cause teeth to become discolored.

Diagnostic Tests for Junctional Epidermolysis Bullosa

Diagnosing JEB involves various tests, such as:

1. Skin Biopsy: A small piece of skin is removed and examined under a microscope.
2. Genetic Testing: Genetic tests can identify specific mutations responsible for JEB.
3. Immunofluorescence Microscopy: This test involves examining skin samples under a special microscope to detect protein abnormalities.
4. Electron Microscopy: It provides detailed images of skin structures.
5. Blood Tests: Blood tests can check for anemia and nutritional deficiencies.
6. Swab Tests: Swabs are taken from the mouth or other affected areas to identify infection.
7. Esophagoscopy: A flexible tube with a camera is used to examine the esophagus.
8. Endoscopy: This procedure involves a thin tube with a camera to examine the digestive tract.
9. Eye Exams: To check for corneal involvement in certain subtypes.
10. X-rays: To evaluate bone and joint conditions.
11. Microbiological Tests: To identify specific pathogens causing infections.
12. Dental Examination: To assess the condition of the teeth.
13. Esophageal Manometry: Measures esophageal function.
14. Skin Culture: Tests for bacterial or fungal infections on the skin.
15. Histological Examination: To study tissue structure.
16. Feeding Evaluation: For infants and children with swallowing difficulties.
17. Prenatal Testing: For families with a history of JEB, prenatal tests can be done to check for genetic mutations.
18. Imaging Studies: Such as ultrasound or MRI to assess internal complications.
19. Eye Pressure Measurement: For detecting corneal abnormalities.
20. Dietary Assessment: To ensure proper nutrition.
