The c.482A>G (p.D161G) alteration is located in exon 6 (coding exon 6) of the TRIP10 gene. This alteration results from a A to G substitution at nucleotide position 482, causing the aspartic acid (D) at amino acid position 161 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
