KCNJ2 wt Allele

**Semantic type:** Gene or Genome

**Definition:** Human KCNJ2 wild-type allele is located in the vicinity of 17q24.3 and is approximately 11 kb in length. This allele, which encodes inward rectifier potassium channel 2 protein, is involved in the establishment of potassium gradient-dependent action potentials across the membranes of excitable cells. Mutation of the gene is associated with long QT syndrome 7 (Andersen syndrome), familial atrial fibrillation 9 and short QT syndrome 3.
