Short answer · Medically reviewed summary · Last updated: 2026-05-08
Holt-Oram syndrome, also known as heart-hand syndrome type I, is a rare genetic disorder characterized by skeletal abnormalities of the upper limbs and congenital heart defects. While the current preferred medical term is Holt-Oram syndrome (often hyphenated), it may appear in older literature or international records under several alternative names reflecting its historical identification. What are the common synonyms for Holt-Oram syndrome? In medical literature, Holt-Oram syndrome is most frequently referred to by its eponymous name, honoring Mary Holt and Samuel Oram, who first described the condition in 1960.

Holt-Oram syndrome, also known as heart-hand syndrome type I, is a rare genetic disorder characterized by skeletal abnormalities of the upper limbs and congenital heart defects. While the current preferred medical term is Holt-Oram syndrome (often hyphenated), it may appear in older literature or international records under several alternative names reflecting its historical identification.
What are the common synonyms for Holt-Oram syndrome?
In medical literature, Holt-Oram syndrome is most frequently referred to by its eponymous name, honoring Mary Holt and Samuel Oram, who first described the condition in 1960. Because it was one of the first recognized genetic syndromes linking specific cardiac and limb malformations, it has been historically referred to as:
- Heart-hand syndrome type I
- Atrio-digital dysplasia
- Cardiac-limb syndrome
- Holt-Oram syndrome (HOS)
Why does Holt-Oram syndrome have multiple names?
The variety of names for Holt-Oram syndrome stems from the evolution of clinical genetics. Before the discovery of the TBX5 gene mutation in 1997, the condition was classified primarily by its physical presentation, leading to descriptive names like "heart-hand syndrome." As clinical classification systems became more standardized, the eponym Holt-Oram syndrome became the global standard to avoid confusion with other, distinct "heart-hand" syndromes that involve different genetic causes.
How is Holt-Oram syndrome classified in medical systems?
To ensure consistency across international medical records, Holt-Oram syndrome is categorized within major databases using specific identifiers. These codes help clinicians and researchers track the condition globally:
- OMIM (Online Mendelian Inheritance in Man): #142900
- Orphanet: ORPHA404
- ICD-10: Q87.2 (Congenital malformation syndromes predominantly involving limbs)
- GARD (NIH): 6653
Next steps
- Consult a clinical geneticist to discuss TBX5 genetic testing.
- Connect with the 76 members of the Holt-Oram syndrome community at DiseaseMaps.org to share experiences and resources.
- Request a referral to a pediatric cardiologist for baseline echocardiography, even in asymptomatic patients.
