ABH antigen secretion in Basques and the spatial variation pattern of the secretor locus in Spain.
Secretion of the ABH blood group antigen was analyzed in 305 saliva samples of students in the Basque Country University. The frequency of ABH non-secretor was 26.23%, a result very close to that obtained in autoctonous Basques (22-23%) and in other populations from the West (Galicia) and Centre (Castille) of Spain. With certain exceptions, the frequencies of non-secretor se allele present a fairly homogeneous variability pattern and no significant spatial orientation or tendencies of se gene distribution are observed in the Iberian Peninsula.
