Abstract
We characterized nearly 500 beta-thalassemia genes from the Israeli population representing a variety of ethnic subgroups. We found 28 different mutations in the beta-globin gene, including three mutations (beta S, beta C, and beta O-Arab) causing hemoglobinopathies. Marked genetic heterogeneity was observed in both the Arab (20 mutations) and Jewish (17 mutations) populations. On the other hand, two ethnic isolates--Druze and Samaritans--had a single mutation each. Fifteen of the beta-thalassemia alleles are Mediterranean in type, 5 originated in Kurdistan, 2 are of Indian origin, and 2 sporadic alleles came from Europe. Only one mutant allele--nonsense codon 37--appears to be indigenous to Israel. While human habitation in Israel dates back to early prehistory, the present-day spectrum of beta-globin mutations can be largely explained by migration events that occurred in the past millennium.This publication has 24 references indexed in Scilit:
