Genes affected

TRMT2A (HGNC:24974): (tRNA methyltransferase 2 homolog A) The protein encoded by this gene is of unknown function. However, it is orthologous to the mouse Trmt2a gene and contains an RNA methyltransferase domain. Expression of this gene varies during the cell cycle, with aberrant expression being a possible biomarker in certain breast cancers. Several transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]

Ambry Genetics

Nov 13, 2024

The c.1595G>A (p.R532Q) alteration is located in exon 11 (coding exon 11) of the TRMT2A gene. This alteration results from a G to A substitution at nucleotide position 1595, causing the arginine (R) at amino acid position 532 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
