BchIDHs
BchIDHs, or B-cell chronic immune dysregulation with hypergammaglobulinemia and hypogammaglobulinemia, is a rare genetic disorder characterized by a combination of immune dysregulation and variable levels of immunoglobulin (Ig) production. The disorder is caused by mutations in the B-cell receptor signaling pathway, specifically in the genes encoding the Bruton's tyrosine kinase (BTK) and the B-cell linker protein (BLNK). These mutations lead to impaired B-cell development and function, resulting in a spectrum of clinical manifestations.
The clinical features of BchIDHs are highly variable and can include recurrent infections, autoimmune manifestations, and
Diagnosis of BchIDHs is typically based on clinical features, laboratory findings, and genetic testing. Laboratory findings
BchIDHs is a complex and heterogeneous disorder that requires a multidisciplinary approach to management. Ongoing research
