The c.1522G>A (p.G508S) alteration is located in exon 9 (coding exon 9) of the TBC1D9B gene. This alteration results from a G to A substitution at nucleotide position 1522, causing the glycine (G) at amino acid position 508 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
