Genes affected

KCNAB3 (HGNC:6230): (potassium voltage-gated channel subfamily A regulatory beta subunit 3) This gene encodes a member of the potassium channel, voltage-gated, shaker-related subfamily. The encoded protein is one of the beta subunits, which are auxiliary proteins associating with functional Kv-alpha subunits. The encoded protein forms a heterodimer with the potassium voltage-gated channel, shaker-related subfamily, member 5 gene product and regulates the activity of the alpha subunit.

The c.458G>A (p.S153N) alteration is located in exon 6 (coding exon 6) of the KCNAB3 gene. This alteration results from a G to A substitution at nucleotide position 458, causing the serine (S) at amino acid position 153 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
