Epidermolysis bullosa (EB) is a genetic skin disorder characterized by skin fragility and blister formation. This review explores the genetic basis and management of EB in the Saudi population, emphasizing the need for genetic insights to enable precise diagnosis, targeted treatments, and effective counseling. Diagnosis in Saudi Arabia relies on clinical assessments and genetic testing. Prenatal diagnosis may be suggested in families with children affected by EB, but it is not widely used in the Middle East. Current management focuses on symptom relief, while emerging experimental approaches such as gene and stem cell therapies are under extensive research. Challenges in EB research include developing effective targeted therapies and understanding the variability in how genotypes manifest phenotypically. Continuous research is crucial to enhance diagnostic methods, therapeutic approaches, and overall patient care.

Dystrophic epidermolysis bullosa (DEB) is a heterogeneous and rare genetic skin disease caused by mutations in the gene, which encodes Type VII collagen. The absence or dysfunction of Type VII collagen can cause the dense lower layer of the basal membrane zone of the skin to separate from the dermis, leading to blister formation and various complications. In different DEB subtypes, the severity of the phenotype is associated, to some extent, with the outcome of Type VII collagen caused by mutations in the gene, which may be reduced in expression, remarkably reduced, or completely absent.

Recessive dystrophic epidermolysis bullosa (RDEB) is caused by mutations in COL7A1, leading to loss or dysfunction of type-VII collagen (C7), a protein essential for skin stability. Clinically, patients suffer from severe skin blistering, chronic or recurrent wounds, and scarring, which predispose to early onset of aggressive squamous cell carcinoma. Previous studies showed that RDEB-keratinocytes (RDEB-KC) express high levels of matrix-metalloproteinase 9 (MMP-9), a molecule known to play a crucial role in wound chronification if dysregulated.

Gene editing technologies, particularly clustered regularly interspersed short palindromic repeats (CRISPR) and CRISPR-associated (Cas) proteins, have revolutionized the ability to modify gene sequences in living cells for therapeutic purposes. Delivery of CRISPR/Cas ribonucleoprotein (RNP) is preferred over its DNA and RNA formats in terms of gene editing effectiveness and low risk of off-target events. However, the intracellular delivery of RNP poses significant challenges and necessitates the development of non-viral vectors.

Background: Epidermolysis bullosa (EB) is a rare genodermatosis that results in extreme skin fragility, for which there is no cure and may be fatal. The quality of life of patients affected may be greatly impacted.
Aim: This study aims to understand the lived experiences of patients with EB.
