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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 22, 2023The c.1370C>T (p.S457F) alteration is located in exon 10 (coding exon 8) of the ADAT1 gene. This alteration results from a C to T substitution at nucleotide position 1370, causing the serine (S) at amino acid position 457 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
