Description

The c.2079C>G (p.S693R) alteration is located in exon 17 (coding exon 17) of the KCNQ2 gene. This alteration results from a C to G substitution at nucleotide position 2079, causing the serine (S) at amino acid position 693 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
