F. Gloriabottini et al., GENETIC INTERACTIONS AND THE ENVIRONMENT - A STUDY OF ADA AND ACP1 SYSTEMS IN THE SARDINIAN POPULATION, Human heredity, 45(3), 1995, pp. 129-134
The pattern of ACP1-ADA association in 12 Sardinian villages is depend
ent on altitude, suggesting that genetic and/or environmental factors
may in fluence the interactions between the two systems, This may expl
ain the variability of the association observed in human populations.
