Ambry Genetics

Dec 19, 2022

The c.2290G>A (p.G764S) 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 2290, causing the glycine (G) at amino acid position 764 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
