Short answer · Medically reviewed summary · Last updated: 2026-05-08
Jarcho-Levin syndrome is a rare congenital disorder characterized by multiple vertebral and rib malformations, often referred to clinically as Spondylocostal Dysostosis (SCD). Because the term Jarcho-Levin syndrome is historically used to describe a broad spectrum of skeletal anomalies, medical professionals now prefer more specific classifications based on the underlying genetic cause, such as SCDO1 through SCDO5. What are the common synonyms for Jarcho-Levin syndrome? In medical literature, you may encounter several names for Jarcho-Levin syndrome.

Jarcho-Levin syndrome is a rare congenital disorder characterized by multiple vertebral and rib malformations, often referred to clinically as Spondylocostal Dysostosis (SCD). Because the term Jarcho-Levin syndrome is historically used to describe a broad spectrum of skeletal anomalies, medical professionals now prefer more specific classifications based on the underlying genetic cause, such as SCDO1 through SCDO5.
What are the common synonyms for Jarcho-Levin syndrome?
In medical literature, you may encounter several names for Jarcho-Levin syndrome. While the eponym honors the physicians who first described the condition in 1938, modern nomenclature prioritizes descriptive terms. Common synonyms and related labels include:
- Spondylocostal Dysostosis (SCD)
- Vertebral-costal anomalies
- Costovertebral segmentation defect
- Jarcho-Levin skeletal dysplasia
Why are there so many names for this condition?
The naming of Jarcho-Levin syndrome has evolved due to advancements in clinical genetics. Historically, many cases of abnormal rib and spine development were grouped under the umbrella of Jarcho-Levin syndrome. However, researchers discovered that these physical traits can be caused by mutations in at least five different genes (e.g., DLL3, MESP2, LFNG). Consequently, the medical community now classifies these as Spondylocostal Dysostosis (SCD) types 1–5 to provide more precise diagnostic and prognostic information.
How is this condition classified in medical databases?
To ensure accuracy in your medical records, it is helpful to know how Jarcho-Levin syndrome is categorized in authoritative systems:
- OMIM (Online Mendelian Inheritance in Man): Categorizes the condition under "Spondylocostal Dysostosis" (e.g., #277300 for SCDO1).
- Orphanet: Uses the identifier ORPHA:2311 for Spondylocostal Dysostosis.
- ICD-10/11: Generally coded under congenital malformation syndromes involving the spine and ribs.
Which name should patients use?
While Jarcho-Levin syndrome remains a common term in patient communities—including among the 5 members of the DiseaseMaps.org platform—your clinical team will likely use "Spondylocostal Dysostosis" in formal reports. Using both terms when speaking with new specialists can help bridge the gap between historical descriptions and modern genetic findings.
Next steps
- Consult a clinical geneticist to determine if your specific diagnosis of Jarcho-Levin syndrome corresponds to a known genetic mutation.
- Request that your medical records include both the eponym and the specific SCD classification for clarity.
