    Summary
    This gene encodes a subunit of a tRNA-specific adenosine deaminase. This heterodimeric enzyme converts adenosine to inosine in the tRNA anticodon. A mutation in this gene causes a syndrome characterized by intellectual disability and strabismus. This gene shares its 5' exon with the overlapping gene, secretory carrier membrane protein 4 (Gene ID: 113178). [provided by RefSeq, Jul 2016]

    4. Study demonstrates that cells isolated from intellectual disability patients with homozygous for the ADAT3-V144M mutation contain diminished levels of wobble inosine in several tRNA isoacceptors. V144M mutation compromises the adenosine deaminase activity of ADAT2/3 complexes, increases the propensity of ADAT3 to oligomerize, and alters the subcellular localization properties of ADAT3.

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
