Abstract
Results of Gc subtyping on 1,222 Israelis, Arabs and Jews, are summarized and their gene frequencies are analyzed in comparison with available data on Gc subtypes in non-Jews. A discriminant and a cluster analysis demonstrated that in their Gc subtype frequencies European and non-European Jews resemble the populations of the areas where they lived before immigrating to Israel. A possible explanation for this resemblance, which is seen in some and not seen in other genetic markers in Jews, is suggested here to be connected with the function of Gc as a vitamin D-binding protein.
