Short answer · Medically reviewed summary · Last updated: 2026-05-08
Acrodysostosis is a rare genetic disorder characterized by skeletal dysplasia, specifically severe peripheral dysostosis, often accompanied by hormonal resistance. The condition is primarily known by its official name, but it has historically been categorized into two subtypes, Acrodysostosis type 1 and Acrodysostosis type 2, based on the underlying genetic mutation. What are the historical and alternative names for Acrodysostosis? Medical literature has historically used several terms to describe Acrodysostosis, which can sometimes lead to confusion in patient records.

Acrodysostosis is a rare genetic disorder characterized by skeletal dysplasia, specifically severe peripheral dysostosis, often accompanied by hormonal resistance. The condition is primarily known by its official name, but it has historically been categorized into two subtypes, Acrodysostosis type 1 and Acrodysostosis type 2, based on the underlying genetic mutation.
What are the historical and alternative names for Acrodysostosis?
Medical literature has historically used several terms to describe Acrodysostosis, which can sometimes lead to confusion in patient records. Older literature often referred to the condition as "Maroteaux-Malamut syndrome" after the researchers who first described it in 1968. While this eponym is rarely used today, you may still encounter it in legacy medical charts or older academic journals. Other descriptive synonyms, such as "peripheral dysostosis with nasal hypoplasia," have been used to define the clinical presentation of Acrodysostosis, though these are now considered outdated descriptions rather than formal diagnostic names.
Why are there different names for Acrodysostosis?
The evolution of names for Acrodysostosis reflects our growing understanding of its genetic basis. Clinicians previously grouped patients based on physical features, but modern classification is driven by molecular diagnostics. The current standard is to classify Acrodysostosis by its specific gene mutation:
- Acrodysostosis type 1 (ACRDYS1): Caused by mutations in the PRKAR1A gene.
- Acrodysostosis type 2 (ACRDYS2): Caused by mutations in the PDE4D gene.
Which name is officially recognized in medical systems?
In global medical databases, Acrodysostosis is the universally accepted terminology. It is indexed in the International Classification of Diseases (ICD) and is the primary entry in Orphanet (ORPHA:1301) and OMIM (#101900, #614613). Medical professionals prefer the term Acrodysostosis paired with the specific genetic subtype, as this nomenclature provides the most accurate guidance for clinical management and genetic counseling.
