Ambry Genetics

Feb 27, 2023

The c.94G>A (p.G32R) alteration is located in exon 1 (coding exon 1) of the SYT16 gene. This alteration results from a G to A substitution at nucleotide position 94, causing the glycine (G) at amino acid position 32 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
