The c.259G>A (p.G87S) alteration is located in exon 2 (coding exon 1) of the CHD9 gene. This alteration results from a G to A substitution at nucleotide position 259, causing the glycine (G) at amino acid position 87 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
