The c.535A>G (p.T179A) alteration is located in exon 4 (coding exon 4) of the TBC1D22A gene. This alteration results from a A to G substitution at nucleotide position 535, causing the threonine (T) at amino acid position 179 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
