Genes affected
TRDMT1 (HGNC:2977): (tRNA aspartic acid methyltransferase 1) This gene encodes a protein responsible for the methylation of aspartic acid transfer RNA, specifically at the cytosine-38 residue in the anticodon loop. This enzyme also possesses residual DNA-(cytosine-C5) methyltransferase activity. While similar in sequence and structure to DNA cytosine methyltransferases, this gene is distinct and highly conserved in its function among taxa. [provided by RefSeq, Jun 2010]

The c.776A>T (p.D259V) alteration is located in exon 8 (coding exon 8) of the TRDMT1 gene. This alteration results from a A to T substitution at nucleotide position 776, causing the aspartic acid (D) at amino acid position 259 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
