Variant summary
Our verdict is Uncertain significance. Variant got 4 ACMG points: 8P and 4B. PVS1BS2
The NM_004700.4(KCNQ4):āc.1668C>Gā(p.Tyr556Ter) variant causes a stop gained change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000434 in 1,613,902 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. Y556Y) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.
