Jul 16, 2024

The c.685C>T (p.R229C) alteration is located in exon 5 (coding exon 4) of the KANSL2 gene. This alteration results from a C to T substitution at nucleotide position 685, causing the arginine (R) at amino acid position 229 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
