Description

The p.I156V variant (also known as c.466A>G), located in coding exon 1 of the KCNJ2 gene, results from an A to G substitution at nucleotide position 466. The isoleucine at codon 156 is replaced by valine, an amino acid with highly similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
