Junctional epidermolysis bullosa (JEB) is a rare genetic skin disease where genetic defects in skin proteins result in extensive blistering in response to mild mechanical stress. Patients are often affected at birth or from early childhood, and suffer from varying degrees of severity depending on the specific mutations that they have and the proteins that are affected. This ranges from severe widespread blistering and death within the first few years of life, to minimal localised blistering and survival to adulthood. Diagnosis is confirmed by genetic testing, and this is often used to predict the likely clinical course. However, it is not always straightforward to make accurate predictions from genetic information, as our understanding of these proteins and mutations at the molecular level is currently incomplete.~The main aim of this project is to systematically collect genetic and clinical data of junctional epidermolysis bullosa (JEB) patients and to explore whether there are any relationships between participants' genetic defects and the severity of disease. This will help in establishing links between genetic defects and clinical characteristics, which is essential for accurate prognostication, genetic counselling and prenatal diagnosis.~This study will also aim to develop pipelines for analysis of how mutations may affect corresponding protein structure and function using computer prediction tools. This will improve our understanding of how these proteins function, and could partly explain the variation in disease severity of patients with this condition. It could also lead to identification of important regions of the protein, which could be investigated further in subsequent studies.
This study will collect genetic and clinical information of junctional epidermolysis bullosa (JEB) patients. Computer analysis will be performed on genetic mutations found in these patients and this will be correlated with their clinical characteristics.
