We hypothesized that such errors in supplementary files might diminish after a report in 2016 highlighting the extent of the problem. To assess this, we performed a scan of supplementary files published in PubMed Central from 2014 to 2020. Overall, gene name errors continued to accumulate unabated in the period after 2016. An improved scanning software we developed identified gene name errors in 30.9% of articles with supplementary Excel gene lists; a figure significantly higher than previously estimated. This is due to gene names being converted not just to dates and floating-point numbers, but also to five-digit numbers. These findings further reinforce that spreadsheets are ill-suited to use with large genomic data.Competing Interest StatementThe authors have declared no competing interest.HGNCHUGO Gene Nomenclature Committee PMC: PubMed CentralJIFJournal Impact FactorHTMLHypertext markup language
