Description

The c.2114G>A (p.R705H) alteration is located in exon 12 (coding exon 12) of the KCNH4 gene. This alteration results from a G to A substitution at nucleotide position 2114, causing the arginine (R) at amino acid position 705 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
