The c.1334A>G (p.Q445R) alteration is located in exon 11 (coding exon 11) of the TRMT13 gene. This alteration results from a A to G substitution at nucleotide position 1334, causing the glutamine (Q) at amino acid position 445 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
