Ambry Genetics

Feb 27, 2024

The c.763A>G (p.I255V) alteration is located in exon 5 (coding exon 5) of the GDE1 gene. This alteration results from a A to G substitution at nucleotide position 763, causing the isoleucine (I) at amino acid position 255 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
