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]

The c.1129C>T (p.R377C) alteration is located in exon 9 (coding exon 9) of the TRMT6 gene. This alteration results from a C to T substitution at nucleotide position 1129, causing the arginine (R) at amino acid position 377 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
