The c.454A>G (p.N152D) alteration is located in exon 6 (coding exon 6) of the TRMT13 gene. This alteration results from a A to G substitution at nucleotide position 454, causing the asparagine (N) at amino acid position 152 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
