Genes affected
TRMT6 (HGNC:20900): (tRNA methyltransferase 6 non-catalytic subunit) This gene encodes a member of the tRNA methyltransferase 6 protein family. A similar protein in yeast is part of a two component methyltransferase, which is involved in the posttranslational modification that produces the modified nucleoside 1-methyladenosine in tRNAs. Modified 1-methyladenosine influences initiator methionine stability and may be involved in the replication of human immunodeficiency virus type 1. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2013]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 09, 2021The c.629C>T (p.A210V) alteration is located in exon 6 (coding exon 6) of the TRMT6 gene. This alteration results from a C to T substitution at nucleotide position 629, causing the alanine (A) at amino acid position 210 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
