What's the significance of having berylliosis?

Beryylium disease. The significance is that the individual now has been diagnosed with a medical condition that may or may not require treatment. "berylliosis" is an old term used to signify acute pulmonary beryllium disease where the person had a fairly large exposure, usually to a more dissolvable form. Chronic beryllium disease typically occurs after frequent but mostly smaller exposures to less soluble forms.
