Ambry Genetics

Feb 22, 2023

The c.2212G>A (p.G738R) alteration is located in exon 12 (coding exon 11) of the TBC1D16 gene. This alteration results from a G to A substitution at nucleotide position 2212, causing the glycine (G) at amino acid position 738 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
