  1. Among tools providing annotations for a specific variant in a tRNA gene (m.4450G>A) chosen for its potential damaging effect, MToolBox showed the widest range of useful features provided in the final annotation step allowing users to prioritize the variant. Empty fields were omitted. Tested tools which do not provide annotations for tRNA variants were not reported
