The c.2446G>C (p.E816Q) alteration is located in exon 12 (coding exon 11) of the KANSL1L gene. This alteration results from a G to C substitution at nucleotide position 2446, causing the glutamic acid (E) at amino acid position 816 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
