Incidence of inherited enzyme activity variants in feral mouse populations

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).
