Announcement

As a result of the significant disruption that is being caused by the COVID-19 pandemic we are very aware that many researchers will have difficulty in meeting the timelines associated with our peer review process during normal times.  Please do let us know if you need additional time. Our systems will continue to remind you of the original timelines but we intend to be highly flexible at this time.

Portable Peer Review

The editors of BMC Genetics support initiatives that expedite the peer review process and are happy to consider manuscripts that have been reviewed in Peerage of Science. Please indicate in your cover letter if this applies to your manuscript.
