Genetic data on the patients with KCNH1 variants. (A, D) Pedigree of the two families. The filled symbol with arrows identifies the probands. (B, E) The variants c.338T>C and c.1069C>T were identified through whole‐exome sequencing and confirmed by Sanger sequencing. The SNVs were shown in gray shadows, c.338T>C was inherited from his mother, and c.1069C>T was de novo. (C, F) The variant amino acids in our patient were conserved from multiple species.
