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 GeneticsJul 20, 2022The c.170T>C (p.I57T) alteration is located in exon 2 (coding exon 2) of the TRDMT1 gene. This alteration results from a T to C substitution at nucleotide position 170, causing the isoleucine (I) at amino acid position 57 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
