Research roundup — September 2026

Papers published this month that name one of the variants MyGeneLog covers, in their title or abstract. This is an index, not a review: the papers are listed, not summarised, assessed or endorsed. Where one of them changes something we publish, that page is updated on its own and carries its own review date.
