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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 22, 2022The c.260G>A (p.R87Q) alteration is located in exon 4 (coding exon 4) of the TRDMT1 gene. This alteration results from a G to A substitution at nucleotide position 260, causing the arginine (R) at amino acid position 87 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
