The c.2035G>A (p.G679R) alteration is located in exon 11 (coding exon 10) of the TBC1D16 gene. This alteration results from a G to A substitution at nucleotide position 2035, causing the glycine (G) at amino acid position 679 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
