Abstract
INTRODUCTION Analysis of fetal DNA in at risk couples for thalassemia is performed from fetal trophoblast or amniotic fluid cells. Although these procedures are in common use, the main limitation is essentially due to the late gestation week in which diagnosis is performed. The celomic cavity develops around 4 weeks of pregnancy within the extraembryonic mesoderm and contains embryonic erythroid precursor cells as a source of fetal DNA that can be used to perform invasive prenatal diagnosis. METHODS Celomatic fluids were obtained at 8 weeks of gestation in thirteen women with high-risk pregnancies. Twelve of these couples were at risk for Hb Lepore disease and β-thalassemia and one couple represented a rare case in which both parents were carriers of Hb Lepore Boston-Washington. Fetal cells were isolated by micromanipulator and nested polymerase chain reactions were performed. RESULTS The analysis was successfully performed in all examined cases. Two fetuses were found to have a compound heterozygosity for β-thalassemia and Hb Lepore Boston-Washington, three fetuses were found to be carriers of β-thalassemia, three fetuses of Hb Lepore, five were found without parental mutations. The genotypic analysis, carried out both by amniocentesis and on abortive tissue or after birth, showed concordance with results obtained on fetal celomic DNA. CONCLUSION Our results unequivocally show that fetal DNA can be obtained by nucleated fetal cells present in celomatic fluid and demonstrate for the first time that prenatal diagnosis of β-thalassemia and Hb Lepore may be feasible in an earlier time of pregnancy than other procedures.

Abstract
Hemoglobinopathies constitute the most common monogenic disorders worldwide, caused by mutations in the globin genes that synthesize the globin chains of hemoglobin. Synthesis may be reduced (thalassemia) or underlie abnormal hemoglobins. Mutation interactions produce a wide range of disorders. For neonatal and antenatal screening, identification of affected newborns or carriers is achieved by hematological tests. DNA analysis supports definitive diagnosis, and additionally facilitates prenatal diagnosis procedures. Most methods used today have been developed over several decades, with few recent advances in hematology methods. However, DNA methods evolve continuously. With global migration and multiethnic societies the trend is from targeted, population-specific methods towards generic methods, such as Sanger sequencing (point mutations) and multiplex ligation probe amplification (deletions). DNA microarrays constitute an advanced DNA method for some mutation categories. The newest DNA technology is next-generation sequencing. Although not completely ready for routine use currently, next-generation sequencing may soon become a reality for some hemoglobin diagnostic laboratories.

Abstract
For definitive diagnosis of thalassemia carriers and patients, as well as for prenatal diagnosis, genotype analysis is of fundamental importance. We report a dry-reagent, lateral flow dipstick test that enables visual genotyping (detection by naked eye) of 15 mutations common in Mediterranean populations in the beta-globin gene (HBB). The method comprises 3 simple steps: (i) PCR amplification of a single 1896 bp segment of the beta globin gene flanking all 15 mutations; (ii) a multiplex (10-plex and/or 30-plex) primer extension reaction of the unpurified amplification product using allele-specific primers. Biotin is incorporated in the extended product; (iii) a dry-reagent multi-allele (10-plex) dipstick assay for visual detection of the primer extension reaction products within minutes. The total time required for PCR, primer extension reaction and the dipstick assay is ~2 h. The method was evaluated by genotyping 45 DNA samples of known genotypes and 54 blind samples. The results were fully concordant with reference methods. The method is simple, rapid, and cost-effective. Detection by the dipstick assay does not require specialized instrumentation or highly qualified personnel. The proposed method could be a particularly useful tool in laboratories with limited resources and a basis for point-of-care diagnostics especially in combination with PCR amplification from whole blood.

Abstract
The variable predisposition of patients, both to disease susceptibility and drug response, is well established. It is largely attributed to genetic, as well as epigenetic variations between individuals, which may be inherited or acquired. The most common variation in the human genome is the SNP, which occurs throughout the genome, both within coding and noncoding regions. Characterization of SNPs in the context of both inherited and acquired conditions, such as cancer, are a main focus of many genotyping procedures. The demand for identifying (diagnosing) targeted SNPs or other variations, as well as the application of genome-wide screens, is continuously directing the development of new technologies. In general, most methods require a DNA amplification step to provide the amounts of DNA needed for the SNP detection step. In addition, DNA amplification is an important step when investigating other types of genomic information, for instance when addressing repeat, deletion, copy number variation or epigenetic regulation by DNA methylation. Besides the widely used PCR technique, there are several alternative approaches for genomic DNA amplification suitable for supporting the detection of genomic variation. In this article, we describe and evaluate a number of techniques, and discuss possible future prospects of DNA amplification in the fields of pharmacogenetics and pharmacogenomics.

Abstract
Implementation of multiplex ligation-dependent probe amplification (MLPA) for thalassemia causing deletions has lead to the detection of new rearrangements. Knowledge of the exact breakpoint sequences should give more insight into the molecular mechanisms underlying these rearrangements, and would facilitate the design of gap-PCRs. We have designed a custom fine-tiling array with oligonucleotides covering the complete globin gene clusters. We hybridized 27 DNA samples containing newly identified deletions and nine positive controls. We designed specific primers to amplify relatively short fragments containing the breakpoint sequence and analyzed these by direct sequencing. Results from nine positive controls showed that array comparative genomic hybridization (aCGH) is suitable to detect small and large rearrangements. We were able to locate all breakpoints to a region of approximately 2 kb. We designed breakpoint primers for 22 cases and amplification was successful in 19 cases. For 12 of these, the exact locations of the breakpoints were determined. Seven of these deletions have not been reported before. aCGH is a valuable tool for high-resolution breakpoint characterization. The combination of MLPA and aCGH has lead to relatively cheap and easy to perform PCR assays, which might be of use for laboratories as an alternative for MLPA in populations where only a limited number of specific deletions occur with high frequency.

Abstract
Disorders of hemoglobin synthesis have been used as a prototype for the development of most approaches for prenatal diagnosis (PND). PND for hemoglobinopathies based on molecular analysis of trophoblast or amniocyte DNA has accumulated approximately 30 years of experience. Disadvantages with conventional PND include 'invasive' fetal sampling and the need to terminate affected ongoing pregnancies. New developments are directed towards improving both the timing and/or safety of procedures. Preimplantation genetic diagnosis, an established procedure with 20 years of clinical application, avoids the need to terminate affected pregnancies through the identification and selective transfer of unaffected in vitro fertilization embryos. Approaches towards 'noninvasive' PND, through analyzing fetal cells or free fetal DNA present in the circulation of pregnant women, are a focus of ongoing research. Overall, PND, preimplantation genetic diagnosis (and potentially 'noninvasive' PND) represent valuable reproductive options for couples at risk of having a child affected with a severe inherited disease.

Abstract
BACKGROUND The detection and diagnosis of β-thalassaemia for populations with molecular heterogeneity, or diverse ethnic groups, has increased the need for the development of an array high-throughput diagnostic tool that can deliver large scale genetic detection. We report on the update and validation of the ThalassoChip, a β-thalassaemia genetic diagnostic tool which is based on arrayed primer extension (APEX) technology. METHODS ThalassoChip slides with new and redesigned probes were prepared for testing the microarray. Six hundred and sixty DNA samples collected from eight Mediterranean countries were used for standardisation, optimisation and validation of the ThalassoChip. The β-globin gene region was amplified by PCR, the products were hybridised to the probes after fragmentation and the APEX reaction followed. RESULTS The ThalassoChip was updated with new probes and now has the ability to detect 57 β-globin gene mutations and three single nucleotide polymorphisms (SNPs) in a single test. The ThalassoChip as well as the PCR and APEX reactions were standardised and optimised using 500 DNA samples that were previously genotyped using conventional diagnostic techniques. Some probes were redesigned in order to improve the specificity and sensitivity of the test. Validation of the ThalassoChip performed using 160 samples analysed in blinded fashion showed no error. CONCLUSIONS The updated version of the ThalassoChip is versatile, robust, cost-effective and easily adaptable, but most notably can provide comprehensive genetic diagnosis for β-thalassaemia and other haemoglobinopathies.
