Ambry Genetics

Jan 17, 2024

The c.221G>A (p.G74E) alteration is located in exon 1 (coding exon 1) of the ADAD2 gene. This alteration results from a G to A substitution at nucleotide position 221, causing the glycine (G) at amino acid position 74 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
