Summary

The Gm(25) allotype has been tested on sera from various populations. It is closely related to Gm(5), Gm(10), Gm(11), and Gm(14) in Caucasoids, and to Gm(10) and Gm(11) in Mongoloids, but it distinguishes itself in Negroids where the Gm(5, 10, 11, 14,-25) phenotype is present with a frequency depending on the regions studied. It was demonstrated to be carried by the Fc fragment of γG2 Gm(5, 10, 11, 14). In a Caucasoid family it was possible to demonstrate the transmission of a rare gene, Gm1,10,11,17, 25. Among Old World Monkeys Gm(25) is present in Baboons and absent in Cercopitheci.

Résumé

L'allotype Gm(25) a été étudié sur des sérums de populations variées. Il est lié aux Gm(5), Gm(10), Gm(11) et Gm(14) chez les Blancs, aux Gm(10) et Gm(11) chez les Jaunes, mais il s'en distingue chez les Noirs où se retrouve le phénotype Gm(5,10,11,14,-25) avec une fréquence variable selon les régions. Il est présent sur le fragment Fc des γG3 Gm(5,10,11, 14). Dans une famille Caucasoide nous démontrons la transmission du rare gène Gm 1,10,11,17,25. L'étude sur des Singes de l'Ancien Monde démontre que le Gm(25) est présent chez les Babouins et absent chez les Cercopithèques.
