aThe ERVK group is referred to as HERV-K(HML-2) according to a nomenclature introduced by Andersson et al. in 1999 [53]. bThe ERVK3 group has been referred to as HERV-K(HML-6) according to the Andersson et al. classification scheme [53]. cThe following loci have not appeared in publications but have been annotated by the RefSeq project: ERVFRD-2 (Entrez Gene:388560); ERVI-1 (Entrez Gene ID:100131068); ERV18-1 (Entrez Gene ID:100133791); ERVMER61-1 (Entrez Gene ID:339476).
