Genes affected
NSUN2 (HGNC:25994): (NOP2/Sun RNA methyltransferase 2) This gene encodes a methyltransferase that catalyzes the methylation of cytosine to 5-methylcytosine (m5C) at position 34 of intron-containing tRNA(Leu)(CAA) precursors. This modification is necessary to stabilize the anticodon-codon pairing and correctly translate the mRNA. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene.[provided by RefSeq, Mar 2011]
LINC01018 (HGNC:27394): (long intergenic non-protein coding RNA 1018)
