Ambry Genetics

Dec 18, 2023

The c.190C>G (p.R64G) alteration is located in exon 1 (coding exon 1) of the GDE1 gene. This alteration results from a C to G substitution at nucleotide position 190, causing the arginine (R) at amino acid position 64 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
