Placental alkaline phosphatase: population studies in Sardinia and data on the anthropological value of this genetic marker.

The analysis of human placental alkaline phosphatase polymorphism in Sardinia has shown a further difference in the genetic structure of this population in comparison with the populations of Continental Italy and Western Europe. Ethnic and geographic variations in world distribution of placental alkaline phosphatase gene frequencies suggest the considerable anthropological value of this genetic marker.
