Ambry Genetics

Dec 16, 2023

The c.1664A>G (p.Y555C) alteration is located in exon 13 (coding exon 11) of the ADAD1 gene. This alteration results from a A to G substitution at nucleotide position 1664, causing the tyrosine (Y) at amino acid position 555 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
