Ambry Genetics

Dec 03, 2021

The c.92G>A (p.R31Q) alteration is located in exon 3 (coding exon 3) of the DDA1 gene. This alteration results from a G to A substitution at nucleotide position 92, causing the arginine (R) at amino acid position 31 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
