The c.1231A>G (p.R411G) alteration is located in exon 3 (coding exon 3) of the TRIM45 gene. This alteration results from a A to G substitution at nucleotide position 1231, causing the arginine (R) at amino acid position 411 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
