Findings

No curated finding names B cell deficiency yet. Everything below is reference data from Mondo, HPO and GenCC, not evidence about what affects it.

Definition

A broad classification of disorders where circulating numbers of B lymphocytes are decreased or ineffective. Complement components and the production of antibodies may also be deficient.
