The c.2569G>A (p.G857S) alteration is located in exon 25 (coding exon 25) of the IPO4 gene. This alteration results from a G to A substitution at nucleotide position 2569, causing the glycine (G) at amino acid position 857 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
