IMMUNOGLOBULIN ALLOTYPES IN EUROPEAN POPULATIONS. IV. Gm,Am AND Km ALLOTYPIC MARKERS IN VALENCIA,SPAIN

The distribution of Glm(f, z, a and x), G3m(b0, b1, b3, b5, c3, c5, g, s and t), A2m (1 and 2) and Km(1) allotypic determinants in a series of Spanish blood donors. The following results were obtained: Gm^z,a;gAm¹= 0.199; Gm^z,a;gAm²= 0.019; Gm^z,a;bAm¹= 0.081; Gm^z,a,x;gAm²= 0.005; Gm^f;bAm¹= 0.677; Gm^z,a;bAm¹= 0.019 and Km¹= 0.096. The results are similar to those reported for adjacent Basque and Portuguese populations. The origin of the Gm^z,a;bAm¹ haplotype is unknown.
