The spectrum of beta-thalassaemia mutations in the Lebanon.
We screened 110 DNA samples from carriers of beta-thalassaemia, using the ARMS-PCR technique with primers for common Mediterranean mutations. Unidentified samples were subjected to a heteroduplex analysis with Universal Heteroduplex Generators covering the beta-globin gene, followed by DNA sequencing. In total, 16 different mutations were detected, the most frequent being IVSI-110 (40%), followed by other common Mediterranean mutations (IVSI-1, IVSII-1, IVSI-6). Other mutations detected were of Lebanese, Turkish, Iranian, Kurdish, Bulgarian and Asian Indian origin. The most heterogeneous religious group seems to be the Sunni Muslims, with 13 mutations, while only 2 mutations were detected among the Christian Maronites. Results from this study are compared with those from other Mediterranean and neighbouring countries.
