Scheme comparing the HERV-W env ORFs from chromosome 7 (syncytin), chromosome X and chromosome 20. Arrows represent transcript origins and asterisks depict stop codons. Black boxes at 1452 nt and at 1515 nt indicate the 12 bp insertion to identify MSRV-like env. Empty boxes: 12 bp deletion. Light and dark gray sequences indicate non homologous sequences compared with syncytin.
