KIT (D816V) Digital PCR in Systemic Mastocytosis
Also known as: cKIT, KIT
Use
Systemic mastocytosis (SM) is a hematopoietic neoplasm characterized by an abnormal growth of clonal mast cells in bone marrow and other extracutaneous organs. Tyrosine kinase inhibitors, such as imatinib and avapritinib, have been evaluated to treat systemic mastocytosis.
