The c.544C>T (p.P182S) alteration is located in exon 7 (coding exon 7) of the TRMT13 gene. This alteration results from a C to T substitution at nucleotide position 544, causing the proline (P) at amino acid position 182 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
