Cutaneous Mastocytosis in Children: Analysis of Somatic and Germline Mutations
Completed
Conditions studied: Urticaria Pigmentosa, Cutaneous Mastocytosis
In brief
Pediatric mastocytosis is an orphan disease, which encompasses several clinically distinct entities including solitary mastocytoma, urticaria pigmentosa, diffuse cutaneous mastocytosis and the newly recognized mast cell activation syndrome. The most common form of pediatric mastocytosis is cutaneous maculopapular mastocytosis (CMPM), also known as urticaria pigmentosa (UP). There are significant knowledge gaps regarding the genetic basis of pediatric mastocytosis and the functional activity of mast cells in this condition. The Pediatric Dermatology and Pediatric Oncology services at the University of Minnesota Masonic Children's Hospital are seeing significant growth in clinical volumes of pediatric mastocytosis, including rare, familial cases. The aims of this study are to prospectively explore germline risk for UP and to perform a mutational analysis to identify somatic mutations, beyond those currently identified, in pediatric patients with UP.
