Andersen-Tawil syndrome synonyms

TL;DR: Andersen-Tawil syndrome is most commonly referred to by its eponymous name, though it is also known as Long QT syndrome type 7 (LQT7). It is a rare genetic disorder characterized by the clinical triad of periodic paralysis, ventricular arrhythmias, and distinct physical (dysmorphic) features.

Why does Andersen-Tawil syndrome have multiple names?

The naming of Andersen-Tawil syndrome reflects the history of medical discovery, where distinct clinical features were initially described separately before being identified as a single, cohesive entity. The condition was first described by Ellen Andersen in 1971 and later expanded upon by Rabab Tawil in 1994, leading to the current eponymous name. Because the condition involves cardiac electrical instability, it is also classified within the spectrum of channelopathies as Long QT syndrome type 7. Having multiple names can be confusing for patients, but it ensures that the condition is categorized correctly within both neurological and cardiological medical literature.

What are the official names and medical classifications?

In global medical databases and classification systems, the condition is consistently recognized to ensure accurate documentation and research tracking. Using the correct terminology is vital when reviewing your own medical records or searching for clinical literature. The following identifiers are used by major health authorities:

• Orphanet: ORPHA:83 (Andersen-Tawil syndrome)


• OMIM (Online Mendelian Inheritance in Man): #170390 (Andersen-Tawil syndrome 1)


• ICD-10/11: Often classified under codes for periodic paralysis or specific cardiac channelopathies (e.g., I47.2 for ventricular tachycardia).

Are there historical or alternative names I should know?

You may encounter older terms in medical textbooks or older journal articles that refer to Andersen-Tawil syndrome. Historically, it was sometimes referred to as "Andersen syndrome" before the contributions of Dr. Tawil were formally recognized in the naming convention. Occasionally, you might see it referred to as "LQT7-periodic paralysis syndrome." It is important to note that while these synonyms describe the same underlying genetic disorder—typically involving mutations in the KCNJ2 gene—the medical community now strongly prefers the term Andersen-Tawil syndrome to provide a standardized, internationally recognized identifier for patients and clinicians alike.
