The c.2857G>A (p.G953S) alteration is located in exon 15 (coding exon 14) of the KANSL1L gene. This alteration results from a G to A substitution at nucleotide position 2857, causing the glycine (G) at amino acid position 953 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
