Ambry Genetics

Feb 21, 2024

The c.617G>A (p.R206H) alteration is located in exon 6 (coding exon 6) of the KHDRBS2 gene. This alteration results from a G to A substitution at nucleotide position 617, causing the arginine (R) at amino acid position 206 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
