Hypothesis
What are the types of mutations occurring in amino acid tandem repeats in the human proteome?
Conclusion
The study reveals diverse mutational dynamics in different types of amino acid repeats, with some being potentially involved in disease.
Supporting Evidence
- Amino acid tandem repeats are found in nearly one-fifth of human proteins.
- The analysis identified 137 polymorphic variants in 115 different amino acid tandem repeats.
- At least about 21% of the repeats might be polymorphic in humans.
Takeaway
Scientists looked at parts of human proteins that repeat and found that they change in different ways, which can sometimes lead to diseases.
Methodology
The study analyzed human expressed sequence tags (ESTs) to identify polymorphic variants in amino acid tandem repeats.
Limitations
The study may have missed some polymorphisms due to the average EST coverage being only 27.4 ESTs per loci.
