Potocki-Lupski syndrome synonyms

Potocki-Lupski syndrome is most commonly referred to by its eponymous name, though it is also formally classified as 17p11.2 duplication syndrome. Because it is a rare genetic condition characterized by a specific chromosomal microduplication, clinicians and researchers prioritize using the official name or the cytogenetic description to ensure medical accuracy in records and research.

What are the official names and synonyms for Potocki-Lupski syndrome?

In medical literature, Potocki-Lupski syndrome is the standard clinical term used to describe the condition. However, because it is defined by a specific genetic change, you will often see it referred to by its cytogenetic location. The most common synonym is 17p11.2 duplication syndrome. In older medical reports or specific genetic databases, you may occasionally encounter the term dup(17)(p11.2p11.2) syndrome. These terms are synonymous and refer to the same clinical entity, which involves the duplication of a small segment of the short arm of chromosome 17.

Why does Potocki-Lupski syndrome have multiple names?

The existence of multiple names for Potocki-Lupski syndrome is primarily due to the evolution of genetic testing and nomenclature. Historically, when clinicians first identified a cluster of symptoms, they often named the condition after the researchers who first described it—in this case, Dr. Lorraine Potocki and Dr. James Lupski. As genomic technology improved, the medical community shifted toward using the exact chromosomal location (17p11.2) to provide a more precise, descriptive identifier. This helps researchers quickly understand the biological mechanism—a duplication of genetic material—without needing to memorize historical eponyms.

How is the condition classified in medical databases?

Standardized medical systems use specific identifiers to track Potocki-Lupski syndrome for clinical and research purposes. Understanding these codes can be helpful when navigating your medical records or insurance documentation:

• OMIM (Online Mendelian Inheritance in Man): The condition is listed as #610883, which is the primary reference for geneticists.


• Orphanet: It is categorized under the code ORPHA:168525, which serves as the international reference for rare diseases.


• ICD-10/11: While there is often no specific code for every rare syndrome, it is frequently grouped under "Chromosomal abnormalities not elsewhere classified."

Which name should patients and families use?

For patients, caregivers, and those connecting with others in the Potocki-Lupski syndrome community, using the name "Potocki-Lupski syndrome" is the most effective way to find resources, support groups, and clinical information. It is the name recognized by the 14 members of the DiseaseMaps.org community who share experiences and insights about the condition. When speaking with medical specialists, such as geneticists or pediatricians, using both the name and the cytogenetic description—"Potocki-Lupski syndrome (17p11.2 duplication syndrome)"—ensures absolute clarity regarding your specific diagnosis.

Next steps

• Consult with a clinical geneticist to confirm your specific genetic report and understand the implications of the 17p11.2 duplication.


• Join the Potocki-Lupski syndrome community on DiseaseMaps.org to connect with others who have navigated similar diagnostic and care journeys.


• Request a referral to a multidisciplinary care team, which may include speech-language pathologists, occupational therapists, and cardiologists, as these specialists are often vital for managing the condition.


• Keep a copy of your genetic testing report in a portable file for use during appointments with new specialists.
