The c.485G>A (p.R162H) alteration is located in exon 5 (coding exon 5) of the TBC1D17 gene. This alteration results from a G to A substitution at nucleotide position 485, causing the arginine (R) at amino acid position 162 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
