Andersen–Tawil syndrome, also called Andersen syndrome and Long QT syndrome 7 which causes muscle weakness, and abnormalities affecting the electrical system of the heart causing abnormal heart rhythms and a variety of facial and skeletal features. These features often include a very small lower jaw, dental abnormalities, low-set ears, widely spaced eyes, and unusual curving of the fingers or toes. It is a rare genetic disorder, and is inherited in an autosomal dominant pattern.
HOW IS ANDERSEN-TAWIL SYNDROME DIAGNOSED?
The diagnosis of Andersen-Tawil syndrome includes details of family and patient history, a rigorous clinical evaluation and some specialized tests which are: • Molecular genetic testing • Electrocardiogram • Long exercise nerve conduction study
HOW IS ANDERSEN-TAWIL SYNDROME TREATED?
There is no treatment available for affected individuals due to the rarity of the syndrome. There are no treatment methods that have been tested on large group of patients. Treatment with an implantable automatic cardioverter-defibrillator or ICD has been used in rare cases. Medications are prescribed to reduce the workload on the heart.
DID YOU KNOW?
The drugs may help the heart, but may have a negative effect on the skeletal system.
