- Type 4 Progressive Osseous Heteroplasia: Characterized by abnormal bone formation within the skin and deeper connective tissues, usually beginning in childhood.
- Type 5 Progressive Osseous Heteroplasia with Pseudohypoparathyroidism: A rare condition that combines features of both progressive osseous heteroplasia and pseudohypoparathyroidism.
