University of Rochester·observational·Posted Aug 28, 2007·Updated Jan 16, 2013

In Brief

An observational study for Andersen-Tawil Syndrome and Andersen Syndrome. Completed, enrolled 28 participants across 7 sites in 4 countries.

Detailed Summary

Andersen-Tawil Syndrome (ATS) is a rare, genetic disorder that causes episodes of muscle weakness, potentially life-threatening changes in heart rhythm, and developmental abnormalities. Disease symptoms can vary, the cause of some ATS cases remains unknown, and no specific treatment has been identified. The purpose of this multi-site study is to better characterize ATS, establish whether symptoms change over time, and determine if symptoms are related to a mutation in the KCNJ2 gene.
