Ambry Genetics

Oct 27, 2023

The c.979T>G (p.C327G) alteration is located in exon 6 (coding exon 6) of the GDE1 gene. This alteration results from a T to G substitution at nucleotide position 979, causing the cysteine (C) at amino acid position 327 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
