Short answer · Medically reviewed summary · Last updated: 2026-05-08
Progressive Osseous Heteroplasia (POH) is a rare genetic disorder characterized by the abnormal formation of bone within soft tissues. While Progressive Osseous Heteroplasia is the current, standard clinical name, it is sometimes historically or colloquially associated with the broader spectrum of Albright hereditary osteodystrophy (AHO) due to overlapping genetic mechanisms. What are the official names and identifiers for Progressive Osseous Heteroplasia? In medical literature and international databases, the official term is Progressive Osseous Heteroplasia.

Progressive Osseous Heteroplasia (POH) is a rare genetic disorder characterized by the abnormal formation of bone within soft tissues. While Progressive Osseous Heteroplasia is the current, standard clinical name, it is sometimes historically or colloquially associated with the broader spectrum of Albright hereditary osteodystrophy (AHO) due to overlapping genetic mechanisms.
What are the official names and identifiers for Progressive Osseous Heteroplasia?
In medical literature and international databases, the official term is Progressive Osseous Heteroplasia. Because it is a rare condition, it is classified under specific codes to ensure accurate medical tracking: the OMIM identifier is #166350, and the Orphanet classification is ORPHA:2804. Clinicians prefer the name Progressive Osseous Heteroplasia because it precisely describes the condition: "progressive" (worsening over time), "osseous" (bone-related), and "heteroplasia" (growth of tissue in an abnormal location).
Why does Progressive Osseous Heteroplasia have different names?
Historically, the nomenclature for Progressive Osseous Heteroplasia was less distinct because it was often confused with other forms of ectopic ossification, such as Fibrodysplasia Ossificans Progressiva (FOP) or general Albright hereditary osteodystrophy. Before the genetic cause (inactivating mutations in the GNAS gene) was fully understood, cases were sometimes grouped under general labels like "progressive bone formation" or "soft tissue ossification." Today, medical professionals use Progressive Osseous Heteroplasia to distinguish it from other conditions that involve bone formation, as the clinical progression and genetic etiology are unique.
What are the common terms and abbreviations used in medical records?
While there are few true "synonyms," you may encounter specific descriptive terms or abbreviations in your medical records:
- POH: The standard clinical abbreviation for Progressive Osseous Heteroplasia.
- Ectopic Ossification: A descriptive term for the process, though it is not a specific name for the disease.
- Heterotopic Ossification: Often used interchangeably in general contexts, though POH is a specific genetic subset.
- GNAS-related disorder: A broad category that includes POH, often used to describe the underlying genetic driver.
