Sequences of the deaminase domains for the indicated proteins were obtained from UniProt database using the accession numbers described for Figure 1. Sequences that are identical are shown in a red-filled box, while those meet consensus (> 70%, <100%) are boxed with consensus residues in red font. Variants in human ADAR1 p150 deaminase domain known to cause AGS (Rice et al., 2012) are indicated using symbols: A870T (#), I872T (*), R892H (!), K999N (^), G1007R(&), Y1112H (+) and D1113H ($). Please refer to Table 1 for detailed information about the consequences of these mutations on ADAR1 function.
