Gene discovered for type 1 diabetes in children
... Hakonarson. However, a special cell type called a natural
killer (NK) cell expresses this gene abundantly, although at different levels based on these gene variants. Our hypothesis is that a special mutation in KIAA0350 may influence the sugar binding of the protein, and trigger an autoimmune response that ...
