Ambry Genetics

Dec 22, 2023

The c.445G>A (p.G149R) alteration is located in exon 3 (coding exon 3) of the DTD2 gene. This alteration results from a G to A substitution at nucleotide position 445, causing the glycine (G) at amino acid position 149 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
