AA numbering is based on Gene Bank cDNA: NM_000238

Nucleotide numbering starts from ATG

RWS = Romano-Ward Syndrome; .DITdP = Drug-induced Torsade de Pointes; SIDS = Sudden Infant Death Syndrome
(1) Only novel mutations reported in this article have been included in the table.
(2)
Found in drug-induced Torsades de Pointes by Paulussen et al. 2004.
(3)
Compund heterozygous with KCNQ1-D611Y
(4)
Homozygous mutation associated with severe in utero and neonatal manifestations.
(5) Comound heterozygous with KCNQ1-R355H and SCN5A-L619F
