Mutation Causes Specific Arrhythmia and Sudden Cardiac Death

An international team of researchers has demonstrated a genetic basis for a fatal form of inherited cardiac arrhythmia that usually strikes young, seemingly healthy people. Basing their research on a French family with a form (Type 4) of inherited Long QT Syndrome (LQTS) and experiments in mice, the researchers found the mutation in a specific gene encoding ankyrin-B, a protein within heart muscle cells. Their discovery identifies what appears to be a novel mechanism for cardiac arrhythmia.
