The c.2038G>C (p.E680Q) alteration is located in exon 11 (coding exon 10) of the TBC1D16 gene. This alteration results from a G to C substitution at nucleotide position 2038, causing the glutamic acid (E) at amino acid position 680 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
