Berylliosis - Definition, Symptoms and Treatment | Beltina.org

Definition of Berylliosis. Berylliosis is chronic damage to the lungs, also called chronic beryllium disease, resulting from industrial exposure to beryllium, a heavy metal that has many commercial uses and applications in contemporary manufacturing processes. Inhaled beryllium fumes and dust cause irritation to the delicate alveoli that activates the body's immune response.

However, the nature of the relationship between exposure and carriage of the DPβE69 genotype has not been well studied.
