The c.686G>A (p.S229N) alteration is located in exon 7 (coding exon 5) of the KIAA0232 gene. This alteration results from a G to A substitution at nucleotide position 686, causing the serine (S) at amino acid position 229 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
