GeneDx RCV000182040 SCV000234343 pathogenic Cardiac arrhythmia 2011-08-14 criteria provided, single submitter clinical testing The c.373_374insGTGG mutation in the KCNH2 gene creates a shift in the reading frame at codon Phenylalanine 125, changing it to a Cysteine, and creating a premature stop codon at position 21 of the new reading frame. Although this mutation has not been reported previously to our knowledge, it is expected to result in an abnormal, truncated protein or in absence of protein from this allele due to mRNA decay, and therefore is interpreted to be a disease-causing mutation. The variant is found in LQT panel(s).
