Estimation of mutation rate from rare protein variants
American Journal of Human Genetics
|May 1, 1977
Summary
This study introduces a new method to estimate protein mutation rates using rare alleles. The new approach, applied to human and macaque data, yields mutation rates of 2-3 x 10^-6 per locus per generation.
Area of Science:
- Population Genetics
- Molecular Evolution
Background:
- Estimating mutation rates is crucial for understanding evolutionary processes.
- Existing methods, like Kimura and Ohta's, have limitations.
Purpose of the Study:
- To present a novel method for estimating mutation rates at protein loci.
- To compare the advantages of the new method over existing ones.
Main Methods:
- Utilizes the count of rare alleles within a population to infer mutation rates.
- Applies the developed method to existing datasets (Neel's and Nozawa's).
Main Results:
- The mutation rate for electrophoretically detectable alleles was estimated to be (2-3) x 10^-6 per locus per generation.
- The new method offers potential advantages over previous approaches.
Conclusions:
- The proposed method provides a viable alternative for mutation rate estimation.
- The estimated mutation rate may exclude severely deleterious mutations.
