The c.1495G>A (p.A499T) 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 1495, causing the alanine (A) at amino acid position 499 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
