Variant summary
Our verdict is Pathogenic. Variant got 14 ACMG points: 14P and 0B. PS1_ModeratePM1PM2PM5PP3_StrongPP5_Moderate
The NM_000238.4(KCNH2):c.1920C>A(p.Phe640Leu) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Another nucleotide change resulting in same amino acid change has been previously reported as Likely pathogenicin ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. F640V) has been classified as Uncertain significance.
