Incidence of inherited enzyme activity variants in feral mouse populations
Biochemical Genetics
|February 1, 1984
Abstract:
We have screened 173 wild caught mice (Mus musculus) from multiple sites in Europe for variation in the activity of 14 enzymes and found 8 different mutants with low enzyme activity; an incidence of 3.69/1000. This compares with the incidence of 3.26/1000 found for low enzyme activity variants in man (Mohrenweiser, 1981).
Insights
Genetic screening of wild mice revealed low enzyme activity mutants, similar to human genetic variation. This research highlights conserved enzyme activity patterns across species.
Area of Science:
- Genetics
- Biochemistry
- Zoology
Background:
- Enzyme activity variations can indicate genetic mutations.
- Understanding these variations is crucial for comparative genomics.
Purpose of the Study:
- To screen wild mice for enzyme activity variations.
- To compare genetic mutation incidence in mice and humans.
Main Methods:
- Screening of 173 wild-caught mice (Mus musculus) from European sites.
- Analysis of 14 different enzyme activities.
- Identification and quantification of low enzyme activity mutants.
Main Results:
- Identified 8 mutants with low enzyme activity.
- Determined an incidence of 3.69 per 1000 for these mutations in mice.
- Compared this incidence to human data (3.26 per 1000).
Conclusions:
- Wild mice exhibit genetic variations in enzyme activity.
- The incidence of low enzyme activity variants in mice is comparable to humans.
- Suggests conserved genetic mechanisms for enzyme activity variation.
