Genes affected

ADAT1 (HGNC:228): (adenosine deaminase tRNA specific 1) This gene is a member of the ADAR (adenosine deaminase acting on RNA) family. Using site-specific adenosine modification, proteins encoded by these genes participate in the pre-mRNA editing of nuclear transcripts. The protein encoded by this gene, tRNA-specific adenosine deaminase 1, is responsible for the deamination of adenosine 37 to inosine in eukaryotic tRNA. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jul 2010]

The c.1351A>G (p.R451G) alteration is located in exon 10 (coding exon 8) of the ADAT1 gene. This alteration results from a A to G substitution at nucleotide position 1351, causing the arginine (R) at amino acid position 451 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
