Epidermolysis Bullosa Letalis

Epidermolysis Bullosa Letalis, commonly called EB, is a severe skin disorder where the skin becomes fragile, easily forming blisters and sores.

Types:

Epidermolysis Bullosa Letalis can be classified into several types, each with its unique characteristics:

  1. Junctional Epidermolysis Bullosa (JEB): This type affects the skin’s junction, where the epidermis and dermis layers meet. It is particularly severe and can lead to life-threatening complications.
  2. Dystrophic Epidermolysis Bullosa (DEB): DEB involves a flaw in the collagen VII protein, causing skin fragility and blistering.
  3. Kindler Syndrome: This is a rare subtype of EBL that includes skin fragility, photosensitivity, and other symptoms.
  4. Non-Herlitz Junctional Epidermolysis Bullosa: This form of JEB is generally milder than Herlitz JEB.
  5. Non-Herlitz Dystrophic Epidermolysis Bullosa: This form of DEB is less severe and may include milder blistering and complications.

Causes:

EBL is primarily caused by genetic mutations, and it is inherited from parents who carry these mutations. The most common cause is a mutation in one of the genes responsible for producing essential skin proteins. These mutations can be passed down through families, and in some cases, they occur spontaneously.

EB is mostly genetic, meaning it’s passed down through families. The skin has proteins holding its layers together. EB patients have genes making these proteins either missing or faulty, leading to skin fragility. Here are 20 associated genes/causes:

  1. KRT5
  2. KRT14
  3. COL7A1
  4. LAMA3
  5. LAMB3
  6. LAMC2
