Bone Dysplasia is a Tier 4 symptom in the Frozen Virus scenario and a Tier 11 symptom in the Necroa Virus DLC. It causes relentless bone growth and musculoskeletal stress.

In Frozen Virus, it cannot be evolved without the DNA Repair 4 ability.

In the Necroa Virus DLC, evolving this alongside Anabolic Boost will unlock the Tank symptom combo.
