Ambry Genetics

Jun 17, 2022

The c.547A>G (p.R183G) alteration is located in exon 4 (coding exon 4) of the NT5DC2 gene. This alteration results from a A to G substitution at nucleotide position 547, causing the arginine (R) at amino acid position 183 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
