Human gene complexity may be underestimated. Alternative splicing and post-transcriptional modifications in the human genome contribute to organismal complexity, impacting disease mechanisms.

Area of Science:

  • Genomics
  • Molecular Biology
  • Human Genetics

Context:

  • Comparative genomics reveals similar gene counts between humans, C. elegans, and Drosophila.
  • Despite similar gene numbers, human complexity is significantly higher.
  • Post-transcriptional regulation plays a crucial role in eukaryotic complexity.

Purpose:

  • To review current knowledge of human gene structure and expression.
  • To highlight the role of post-transcriptional mechanisms in human complexity.
  • To focus on mechanisms contributing to human diseases.

Summary:

  • Human genome gene count is comparable to simpler organisms like C. elegans and Drosophila.
  • Alternative splicing and post-transcriptional modifications significantly increase human proteomic diversity.
