Category:B cell linker protein deficiency

A hypobammaglobulinemia that is a B cell deficiency caused by a mutation a cytoplasmic linker or adaptor protein that plays a critical role in B cell development, the B cell linker protein (BLNK) gene. Mutations in this gene cause hypoglobulinemia and absent B cells, a disease in which the pro- to pre-B-cell transition is developmentally blocked. The BLNK gene is associated with intracellular calcium mobilization, essential for cell activation.
