Ambry Genetics

Oct 20, 2024

The c.677G>A (p.R226K) alteration is located in exon 9 (coding exon 7) of the KDM1B gene. This alteration results from a G to A substitution at nucleotide position 677, causing the arginine (R) at amino acid position 226 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
