We present the characterization of the molecular spectrum and frequency data of alpha-thal (thal) defects in Tunisia, and an evaluation of the efficacy and limitations of Hb Bart's (gamma4) measurement for the screening of alpha-thal at birth. Cord blood samples were collected from two different areas: the northeast of the country, an area where Hb H(More)
The polycystic kidney disease-1 gene, which is mutated in the majority of patients with autosomal dominant polycystic kidney disease, has been identified. The protein encoded by this gene, polycystin, has no homology with any gene known thus far. To gain more insight into the function of polycystin, we raised antibodies against synthetic peptides and a(More)
OBJECTIVE As a result of global population movements, haemoglobin disorders (thalassaemias and sickle cell disorders) are increasingly common in the formerly non-indigenous countries of Northern and Western Europe and in the indigenous countries of Southern Europe. This article presents an overview of the changing picture and a method for assessing service(More)
The analysis of polymerase chain reaction (PCR)-amplified beta-globin DNA with allele-specific oligonucleotide (ASO) probes reveals a very heterogeneous spectrum of beta-thalassaemia in the Netherlands. However about 20% of the beta-thalassemia mutations cannot be identified with this approach. The combination of specific amplification of certain regions of(More)
The presence of several polymorphic markers along the alpha-globin gene complex allows the identification of haplotypes associated with alpha-thalassemia determinants. These are found at very high frequencies in geographic areas where malaria is or has been endemic which suggests a positive selective role by the parasitic disease in favour of(More)
BACKGROUND Approximately 80% of the alpha- and 10% of the beta-thalassaemias are caused by genomic deletions involving the alpha- and beta-globin gene clusters on chromosomes 16p13.3 and 11p15.5, respectively. Gap-PCR, Southern blot analysis, and fluorescent in situ hybridisation are commonly used to identify these deletions; however, many deletions go(More)
BACKGROUND AND OBJECTIVES Hydroxyurea (HU) is known to increase gamma-globin chain expression in postnatal life. The efficacy of HU treatment in thalassemia patients is still unclear. The aim of this study was to monitor treatment of a large cohort of patients with beta-thalassemia major in order to establish the response to HU and the associated elements.(More)

We describe here the screening of a small group of apparently healthy individuals belonging to the tribal communities of Koya Dora and Konda Reddi. A remarkably high incidence of deletion and nondeletion α+ thalassemia mutants has been found with allele frequencies and distributions characteristic to each tribe. We have confirmed the strict relationship(More)
The number of immigrants in Western Australia from many different areas where hemoglobinopathies are endemic has increased dramatically since the 1970s. Therefore, many different thalassemia mutations have been introduced in the country, which add a technological diagnostic problem to the serious burden of hemoglobinopathy management and to public health(More)
