Mean (± SEM) values of mannan-binding lectin (MBL) level in patients with hypopituitarism (n=42) who are on appropriate replacement therapies (compensated hypopituitarism, n=10) vs. inadequate replacement therapies (non-compensated hypopituitarism, n=32) presented in particular subgroups of individuals depending on how many pituitary axes are involved. This evidence concerns the gene MBL2 and hypopituitarism.
