Isolated polynucleotide molecules, and peptides encoded by these molecules, are used in the analysis of human cardiac potassium channel minK subunit variants, as well as in screening and diagnostic applications relating to a D85N polymorphism in the KCNE1 gene encoding the human cardiac potassium channel minK subunit polypeptide. By analyzing biological samples from a subject, it is possible to type a human cardiac potassium channel minK subunit with regard to the KCNE1-D85N polymorphism, for example, in the context of screening for susceptibility to drug-induced cardiac arrhythmias. |
