  Purpose

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.

Further study details as provided by University of Zurich:

Primary Outcome Measures:
  • Enrichment of rare coding genetic variants [ Time Frame: baseline ] [ Designated as safety issue: No ]
    Whole exome sequencing is going to detect rare coding genetic variants in cases of Neutrophil-Mediated Inflammatory Skin Diseases. Statistical burden tests are applied to test for excess of rare variants in cases versus available controls of matching ancestry.
