Ambry Genetics

Jul 20, 2021

The c.2021G>A (p.R674Q) alteration is located in exon 9 (coding exon 9) of the ADARB2 gene. This alteration results from a G to A substitution at nucleotide position 2021, causing the arginine (R) at amino acid position 674 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
