Description

The stop gained variant in c.232A>T (p.Lys78Ter) in KCNQ4 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The nucleotide change in KCNQ4 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. The variant is novel (not in any individuals) in gnomAD Exomes and 1000 Genomes. For these reasons, this variant has been classified as Uncertain Significance .
