Nine human retrogenes that gained introns investigated in this study
Retrogene Parent Movement Intron (+) Intron (−) Evidence
TMEM14D TMEM14B 10 < −6 1 4 A
RPS3AP5 RPS3A 10 < −4 1 5 B
XXyac-R12DG2.2 RCN1 13 < −11 2* 5 B
HSP90B2P HSP90B1 15 < −12 2 16 B
HSP90AA4P HSP90AA1 4 < −14 3 9 A,B
HSP90AA5P HSP90AA1 3 < −14 2 7 B
CSMD3 RPL18 8 < −19 1 5 B
WBP2NL SLC25A5 22 < −X 1 3 B
AC019016.1 CSNK1A1 15 < −5 2* 8 B

In the column ‘Movement’, ‘10 < −6’ means a new gene on chromosome 10 is retroposed from a gene on chromosome 6, for example. ‘Intron (−)’ and ‘Intron (+)’ are the numbers of intron losses and intron gains in retrocopies, respectively. For ‘Evidence’, ‘A’, confirmed by RT-PCR; ‘B’, supported by convincing transcription evidence. ‘*’ means that the newly evolved intronic regions of XXyac-R12DG2.2 and AC019016.1 could be spliced in two patterns, respectively.
