Molecular assay reagents intended to identify gene variants associated with long QT syndrome, a condition characterized by episodic syncope (i.e., fainting) and a prolonged QT interval on an electrocardiogram. Genetic variants at multiple loci have been associated with various forms of long QT Syndrome (e.g., Romano-Ward Syndrome, Jervell-Lange Nielson Syndrome). These reagents are intended to detect various types of genetic changes (e.g., deletions, duplications, insertions, single nucleotide polymorphisms) in multiple long QT syndrome-associated loci simultaneously.
