%0 Journal Article %T A novel 8-bp duplication in ADAT3 causes mild intellectual disability %J - %D 2018 %R https://doi.org/10.1038/s41439-018-0007-9 %X Inosine is a base located at wobble position 34 of the tRNA anticodon stem¨Cloop, enabling the recognition of more than one codon in the translation process. A heterodimer consists of ADAT3 and ADAT2 and is involved in the adenosine-to-inosine conversion in tRNA. Here, we report the second novel ADAT3 mutation in a patient with microcephaly, intellectual disability, and hyperactivity. These findings constitute a second mutation and expand the clinical spectrum of extremely rare ADAT3 mutations %U https://www.nature.com/articles/s41439-018-0007-9
