Short answer · Medically reviewed summary · Last updated: 2026-05-08
Chondrodysplasia punctata (CDP) is a group of rare skeletal disorders characterized by abnormal calcification of cartilage, traditionally referred to as "stippled epiphyses." Because chondrodysplasia punctata represents a heterogeneous group of genetic conditions rather than a single disease, it is often categorized by its underlying genetic cause, such as X-linked recessive or rhizomelic forms. What are the common synonyms and historical names for Chondrodysplasia Punctata? In medical literature, chondrodysplasia punctata has historically been referred to as Conradi-Hünermann syndrome or Conradi-Hünermann-Happle syndrome. You may also encounter the term "stippled epiphyses" in older clinical reports, which describes the radiographic appearance of the bone.

What are the common synonyms and historical names for Chondrodysplasia Punctata?
In medical literature, chondrodysplasia punctata has historically been referred to as Conradi-Hünermann syndrome or Conradi-Hünermann-Happle syndrome. You may also encounter the term "stippled epiphyses" in older clinical reports, which describes the radiographic appearance of the bone. Due to the diverse genetic origins of chondrodysplasia punctata, clinicians often use specific subtypes like X-linked dominant chondrodysplasia punctata (CDPX2) or rhizomelic chondrodysplasia punctata (RCDP) to provide more diagnostic precision.
Why does this condition have multiple names?
The naming of chondrodysplasia punctata has evolved as genetic research identified distinct metabolic pathways. Initially, the condition was classified purely by its physical appearance on X-rays. As we identified the specific enzyme deficiencies—such as those involving peroxisomal metabolism—the nomenclature shifted to prioritize the molecular cause. This transition helps medical professionals differentiate between the various forms of chondrodysplasia punctata, which have vastly different clinical trajectories and inheritance patterns.
How is the condition classified in medical systems?
Major international classification systems organize these disorders to reflect their genetic heterogeneity:
- OMIM (Online Mendelian Inheritance in Man): Assigns unique numbers to each subtype (e.g., OMIM #302960 for CDPX2).
- Orphanet: Lists the condition under the umbrella of skeletal dysplasias, with specific entries for rhizomelic and non-rhizomelic forms.
- ICD-10/11: Codes such as Q77.3 are used to identify chondrodysplasia punctata in clinical billing and medical record documentation.
Next steps
- Consult with a clinical geneticist to determine the specific subtype of chondrodysplasia punctata affecting your family.
- Request a referral to a metabolic specialist if a peroxisomal disorder is suspected.
