Description

The p.S64I variant (also known as c.191G>T), located in coding exon 1 of the KCNE1 gene, results from a G to T substitution at nucleotide position 191. The serine at codon 64 is replaced by isoleucine, an amino acid with dissimilar properties. This amino acid position is conserved. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
