ers-2 was an other name of qrs-3 but has been update as ers-2(main name), qrs-3(other-name). ers genes have similarity to both glutamyl tRNA synthetases (ers-) and glutaminyl tRNA synthetases (qrs-). The ers gene class description is thus updated to glutamyl(E)/glutaminyl(Q) aa-tRNA Synthetase
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
