Polymorphism of the gene encoding a human minimal potassium ion channel (minK)

Abstract

A gene (minK) that encodes a minimal potassium channel has been cloned recently. We describe in this paper a human minK sequence which differs from the original sequence with a single A-->G at position 112. This resulted in a change from a Ser codon (AGT) to a Gly codon (GGT) and created a new MspAI restriction site. Of the 32 alleles from 16 subjects studied, 25 had this newly discovered sequence and 7 had the previously described sequence.
