Other Specified Inflammatory Disorders of Skin or Subcutaneous Tissue | Observational Study of the Genetic Architecture of Neutrophil-Mediated Inflammatory Skin Diseases

Other Specified Inflammatory Disorders of Skin or Subcutaneous Tissue research study

What is the primary objective of this study?

This study investigates the genetic architecture of Neutrophil-Mediated Inflammatory Skin Diseases. After collecting informed consent, all patients' clinical phenotype is graded at inclusion with a detailed case report form and a discovery cohort formed based on the certainty of diagnosis. The DNA of patients in the discovery cohort is analyzed by whole exome sequencing which identifies all protein-coding genetic variants. Subsequently, statistical burden tests are going to identify enrichment of rare coding genetic variants in patients affected by Neutrophil-Mediated Inflammatory Skin Diseases. The ultimate goal is to reveal the responsible gene(s) that may then be targets for clinical intervention.

Who is eligible to participate?

Inclusion criteria: - History of NMID or active disease. - Informed consent. Exclusion criteria: - No consent to either part of the study.
