Abstract

Globin gene mapping analyses of DNA from numerous Black babies, and from newborns from Sardinia, Sicily, Turkey, and Spain have identified the following A high incidence of αthalassemia-2 heterozygotes among Black babies with less than 1% Hb Bart's at birth and a high incidence of αthalassemia-2 among Sardinians, but not among Sicilian, Turkish, and Spanish babies. A relatively high incidence of ζthalassemia was present among Black babies only, while triplicated ζ was seen in four of the five populations. Two Black babies were each found to have a different θl deletion; two Sardinian babies had a newly discovered β 2.5 kb deletion between ζ and ψzeta;; four babies had the rare Bgl II polymorphism between ψzeta; and ψalpha;; and one Black baby lacked the Eco RI site 3> to ζ Quantitation of the ζ chain by reversed phase high performance liquid chromatography showed that two-thirds of the babies with four α genes (αalpha;alpha;alpha; had levels between 0.1 and 1.0% while nearly 90% of the babies with -αalpha;alpha; had similar levels (averaging 0.2% for αalpha;alpha;alpha; 0.35% for -αalpha;alpha; 0.75% for -αalpha; Additional data indicated that the occurrence and level of ζ are related to the level of β i.e. the gestational age. The presence of a ζ triplication did not affect the level of ζ in cord blood. The extensive search for γglobin gene anomalies resulted in the discovery of a chromosome with five γ genes, γThalassemia was rare in all populations, while the -GγGγ gene arrangement was mainly observed among Black babies; this arrangement is primarily responsible for high Gγ levels in cord blood samples. The strong correlation between the presence or absence of a C→T mutation at position -158 (measured in Xmn I digests) and the level of Gγ was confirmed for adult blood samples. A search for possible anomalies in the -δbeta; region through gene mapping with Eco RV gave negative results except for the discovery of a polymorphic site 5> to δ in one of the 371 Black babies tested.
