Abstract

Regulatory variation influencing gene expression is a key contributor to phenotypic diversity, both within and between species. Unfortunately, RNA degrades too rapidly to be recovered from fossil remains, limiting functional genomic insights about our extinct hominin relatives. Many Neanderthal sequences survive in modern humans due to ancient hybridization, providing an opportunity to assess their contributions to transcriptional variation and to test hypotheses about regulatory evolution. We developed a flexible Bayesian statistical approach to quantify allele-specific expression (ASE) in complex RNA-seq datasets. We identified widespread expression differences between Neanderthal and modern human alleles, indicating pervasive cis-regulatory impacts of introgression. Brain regions and testes exhibited significant downregulation of Neanderthal alleles relative to other tissues, consistent with natural selection influencing the tissue-specific regulatory landscape. Our study demonstrates that Neanderthal-inherited sequences are not silent remnants of ancient interbreeding but have measurable impacts on gene expression that contribute to variation in modern human phenotypes.

  • Neanderthal ancestry is depleted in regions of the genome with annotated molecular functions, and this depletion is strongest in annotated brain and testis regulatory regions.

    “Second, Neanderthal ancestry is depleted in regions of the genome with annotated molecular functions (e.g., genes and gene regulatory elements), and this depletion is strongest in annotated brain and testis regulatory regions27–29.”

    From Quantifying the contribution of Neanderthal introgression to the heritability of complex traits (2021) · cites this paper as [28]

    In Results and Discussion, “Neanderthal alleles are down-regulated in the testes” (page unavailable), the paper states that genes highly expressed in testes are depleted of Neanderthal ancestry. Its brain and testes analyses report stronger downregulation of introgressed alleles, which is not the same as depletion of ancestry from regulatory regions. The passages do not establish genome-wide depletion from annotated functional regions or that depletion is strongest in brain and testis regulatory regions. (LLM, conf=0.87)

  • The depletion in cognitive traits suggests that the previously observed strong depletion for Neanderthal alleles in regulatory regions active in the brain may be due to effects on brain-related complex traits.

    “The depletion in cognitive traits suggests that the previously observed strong depletion for Neanderthal alleles in regulatory regions active in the brain may be due to effects on brain-related complex traits5,28,29.”

    From Quantifying the contribution of Neanderthal introgression to the heritability of complex traits (2021) · cites this paper as [28]

    In Results and Discussion, “Brain sub-regions show downregulation of Neanderthal alleles” (page unavailable), the paper reports lower expression of introgressed alleles in brain regions and notes the cognitive functions of some of those regions. Downregulation of allelic expression is not the claimed depletion of Neanderthal alleles from brain-active regulatory regions; the paper also does not link that depletion to effects on brain-related complex traits. (LLM, conf=0.81)

    Experimental — accuracy not yet measured
  • Studies conducted primarily on Neanderthal introgressed DNA have suggested a non-negligible contribution to gene expression variation in modern humans, with repeated examples of Neanderthal archaic variants falling within regulatory elements or the seed region of mature micro-RNAs predicted to affect transcriptional and post-transcriptional regulatory processes.

    “Indeed, studies conducted primarily on Neanderthal introgressed DNA have suggested a non-negligible contribution to gene expression variation in modern humans [10, 11, 22], with repeated examples of Neanderthal archaic variants falling within regulatory elements or the seed region of mature micro-RNAs predicted to affect transcriptional and post-transcriptional regulatory processes [11, 62].”

  • Enhancers are among the top targeted elements of archaic hominin introgression.

    “Enhancers, in particular, are amongst the top targeted elements of archaic hominin introgression [10, 11].”

    From Denisovan introgression has shaped the immune system of present-day Papuans (2022) · cites this paper as [10]

    The Introduction says Neanderthal-introgressed sequences encompass functional genomic features, but does not rank enhancers among them. The Results and Discussion section on regulatory effects compares allele-specific expression, not which genomic elements were most targeted by introgression. Searches for enhancers and their enrichment found no passage establishing the claimed ranking. (LLM, conf=0.76)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
