Abstract
BACKGROUND Primary ovarian insufficiency (POI) is defined as a primary ovarian defect characterized by absent menarche (primary amenorrhea), a decrease in the initial primordial follicle number, high follicle-stimulating hormone (FSH) levels and hypoestrogenism. Although the etiology of a majority of POI cases is not yet identified, several data suggest that POI has a strong genetic component. Conventional cytogenetic and molecular analyses have identified regions of the X chromosome that are associated with ovarian function, as well as POI candidate genes, such as FMR1 and DIAPH2. Here we describe a 10.5-year-old girl presenting with high FSH and luteinizing hormone (LH) levels, pathologic GH stimulation arginine and clonidine tests, short stature, pterygium, ovarian dysgenesis, hirsutism and POI. RESULTS Cytogenetic analysis demonstrated a balanced reciprocal translocation between the q arms of chromosomes X and 1, with breakpoints falling in Xq21 and 1q41 bands. Molecular studies did not unravel any chromosome microdeletion/microduplication, and no XIST-mediated inactivation was found on the derivative chromosome 1. Interestingly, through immunofluorescence assays, we found that part of the Xq21q22 trait, translocated to chromosome 1q41, was late replicating and therefore possibly inactivated in 30 % metaphases both in lymphocytes and skin fibroblasts, in addition to a skewed 100 % inactivation of the normal X chromosome. These findings suggest that a dysregulation of gene expression might occur in this region. Two genes mapping to the Xq translocated region, namely DIAPH2 and FMR1, were found overexpressed if compared with controls. CONCLUSIONS We report a case in which gonadal dysgenesis and POI are associated with over-expression of DIAPH2 gene and of FMR1 gene in wild type form. We hypothesize that this over-expression is possibly due to a phenomenon known as "chromosomal position effect", which accounts for gene expression variations depending on their localization within the nucleus. For the same effect a double mosaic inactivation of genes mapping to the Xq21-q22 region, demonstrated by immunofluorescence assays, may be the cause of a functional Xq partial monosomy leading to most Turner traits of the proband's phenotype.

Abstract
The 22q11.2 microduplication is a genomic disorder, characterized from a variable phenotype ranging from different defects to normality. The most common microduplication of 22q11.2 is 3 Mb in size, but there are also cases reported with atypical duplications between 0.8 Mb and 6Mb. Here, we describe a case of a child with macrocephaly, overgrowth with advanced bone age, attention deficits, evidence of mild mental retardation and dysmorphic features. An array-CGH analysis detected a 252 Kb duplication at the 22q11.2 region inherited from mother and 142 Kb duplication at 8q22.1 region inherited from father. Both parents show mild dysmorphic features. The duplicated genes in chromosomes 22q and 8q are TOP3B and PGCP, respectively. We describe for the first time a patient carrying the smaller atypical 22q11.2 duplication who also presents with mild mental retardation and generalized overgrowth. This patient has an additional duplication in 8q22.1 which may act as a genomic modifier of its clinical phenotype.

Abstract
BACKGROUND Partial monosomies of chromosome 16q are rare and overlapping effects from complex chromosomal rearrangements often hamper genotype-phenotype correlations for such imbalances. Here, we report the clinical features of an isolated partial monosomy 16q21q22.1 in a boy with a complex de novo rearrangement possibly resulting from a chromothripsis event. RESULTS The patient presented with low birth weight, microcephaly, developmental delay, facial dysmorphisms, short stature, dysmorphic ears and cardiopathy. Standard and molecular cytogenetics showed a complex rearrangement characterised by a pericentromeric inversion in one of chromosomes 12 and an inverted insertional translocation of the 12q14q21.1 region, from the rearranged chromosome 12, into the q21q22.1 tract of a chromosome 16. Array-CGH analysis unravelled a partial 16q21q22.1 monosomy, localised in the rearranged chromosome 16. CONCLUSIONS The comparison of the present case to other 16q21q22 monosomies contributed to narrow down the critical region for cardiac anomalies in the 16q22 deletion syndrome. However, more cases, well characterised both for phenotypic signs and genomic details, are needed to further restrict candidate regions for phenotypic signs in 16q deletions. The present case also provided evidence that a very complex rearrangement, possibly caused by a chromothripsis event, might be hidden behind a classical phenotype that is specific for a syndrome.

Abstract
Hb City of Hope [beta 69(E13)Gly----Ser] was detected by reversed phase high performance liquid chromatography in an asymptomatic carrier from Naples, Southern Italy. The amino acid substitution, identified by fast atom bombardment mass spectrometry, was due to a TGG----TGA substitution as assessed by DNA sequencing. Analysis of the chromosomal background indicates that the globin gene cluster containing the mutant gene has most probably been rearranged by a recombination event, since the mutation was associated with restriction fragment length polymorphism haplotype IX, instead of haplotype I, as previously reported.

Abstract
Between January 1995 and December 2005, we conducted a screening program for the presence of Hb Neapolis, a rare abnormal Hb variant, in Campania, a region in Southern Italy. Nineteen patients with Hb Neapolis in heterozygosis and six patients with a genetic compound (Hb Neapolis/beta-thalassemia) were identified. Patients with Hb Neapolis in heterozygosis showed a slight alteration in HbA2 levels while compounds showed typical characteristics of thalassemia intermedia ranging from a non transfusion-dependent form for five patients to a transfusion-dependent form for one adult patient.

Abstract
Twelve patients with different features of Turner syndrome, and with Xp and Yp rearrangements involving the pseudoautosomal region (PAR1) are described. In all patients, FISH analysis showed loss of one copy of the Short Stature Homeobox (SHOX)-containing gene. Ten patients had short stature and one disproportionate (mesomelic) normal stature, while the last one had normal stature. Skeletal abnormalities, including shortened ulna, were detected in nine subjects, and in six of them Madelung deformity was observed. These clinical data indicated a genotype phenotype correlation between haploinsufficiency of SHOX, and short stature and skeletal abnormalities.

Abstract
PURPOSE To evaluate the efficacy and toxicity of a sequential low-dose methotrexate (MTX) and 5-fluorouracil (5FU) regimen in the palliative treatment of patients with advanced colorectal cancer. PATIENTS AND METHODS Enrolled in the study were patients with advanced colorectal cancer, refractory to 5FU + FA. Patients were treated with MTX 40 mg/m2 i.v. bolus d 1 and 8, 5FU 700 mg/m2 i.v. bolus d 2 and 9 (24 hours after MTX bolus). The cycle was repeated every 4 weeks. RESULTS 48 patients entered the study, and 45 are evaluable. The overall response rate was 15% with 1 complete response and 6 partial responses. Eight patients obtained disease stabilization. Median time to progression was 9 months. Toxicity was mild. Grade 3 stomatitis was observed in 7 (15%) patients. CONCLUSIONS Sequential MTX/5FU is a well tolerated regimen with mild antitumor activity in refractory advanced colorectal patients.

Abstract
The simultaneous presence of two hemoglobin variants has been detected in a 14-month-old patient affected by thalassemia intermedia. The two variants were characterized by a combination of allele-specific amplification methods and mass spectrometric procedures carried out on isolated globins. These were identified as Hb Lepore-Boston and Hb Neapolis (also known as Hb Dhonburi) or beta 126 (H4)Val-->Gly. Hb Lepore-Boston is the most common hybrid variant detected in Campania and several cases of Hb Neapolis which causes a mild hypochromic microcytic anemia have been identified in this region in the last few years. This is the first report of a double heterozygosity involving Hb Lepore-Boston and Hb Neapolis.

Abstract
Hb O-Arab [beta 121(GH4)Glu-->Lys] was detected in two Mediterranean families, one from Southern Italy and the other from Albania. The GAA-->AAA mutation at codon 121 was characterized by DNA sequencing. The mutant genes were associated with the same beta-globin gene framework variant and with the rare Hpa I/3' beta polymorphic restriction site generating a 7.0 kb fragment. However, at 5' the gene of the Italian family was associated with the restriction fragment length polymorphism subhaplotype [+ - - - +] and the Taq I/3'G gamma polymorphic site, while that of the Albanian family was associated with subhaplotype [- - - - +] but not with the Taq I/3'G gamma site. The particular features of these polymorphisms support the hypothesis of an African origin for the Hb O-Arab gene and a subsequent recombination event leading to the haplotype found in the Italian family.

Abstract
We detected Hb D-Los Angeles [beta 121(GH4)Glu-->Gln], the most common hemoglobin variant after Hb S and Hb Lepore-Boston, in six unrelated families in Southern Italy. Ten patients were studied; eight patients were heterozygotes and two were compound heterozygotes for the hemoglobin variant and the beta-thalassemia codon 39 (C-->T) nonsense mutation. The beta-globin gene sequence was characterized by polymerase chain reaction direct sequencing; restriction fragment length polymorphisms were defined by Southern blot analysis. The gene variant, due to the GAA-->CAA substitution at codon 121, was found in association with the 5' subhaplotype [+ - - - -] and the beta-globin gene framework 1; in addition, it was found to be associated with the absence of Ava II/phi beta and Xmn I/5'G gamma, and with the presence of Hpa I/3' beta. This restriction fragment length polymorphism haplotype is common in the Mediterranean area as well as in other populations. The findings are equally compatible with an independent origin in the Mediterranean area or with origin in Asia and subsequent spread to Italy.

Abstract
Forty-three hybrid delta-beta-globin genes were characterized by DNA sequence analysis and associated RFLP haplotypes in 40 families from Abruzzo and Campania, which are on the east and west coast of Italy, respectively. All the genes had the delta-globin sequence up to the exon 2 codon 87 and had the beta-globin sequence from IVS-2-8; between these two ends, they had 58 bp in common with the delta- and beta-globin genes. Thus, they were all of the Lepore-Boston type. A chromosomal background heterogeneity was present among the mutant genes. In fact, they were all associated with (+ - - - -) 5' subhaplotype, but 23/31 from Campania were associated with (+ +) 3' subhaplotype, whereas 12/12 genes from Abruzzo and 8/31 from Campania were associated with (+ -). DNA sequencing of homozygous subjects showed that (+ +) 3' subhaplotype was associated, at IVS-2-74, with G, while (+ -) was associated with T; that is they were associated with the beta-globin gene sequence of frameworks 1 and 2, respectively. The molecular characteristics of this heterogeneity, as well as its geographical patterns in the eastern and western regions of Italy, represent strong evidence for the recurrent and multicentric origins of the mutation.

Abstract
A novel beta-chain, beta 126(H4)Val----Gly, electrophoretically silent, was detected by reverse-phase high performance liquid chromatography in three unrelated families from Naples (Southern Italy) and accounted for about 30% of the total beta-chains. The amino acid substitution was detected by HPLC fingerprint. The eight heterozygous patients showed hematologic and biosynthetic alterations of mild beta-thalassemia type. The hemoglobin variant showed abnormal stability features. It was unstable in the heat stability and isopropanol precipitation tests, but did not cause a hemolytic syndrome in vivo and was stable in a time-course experiment of biosynthesis in vitro. DNA polymerase chain reaction direct sequencing of the mutated gene from 135 nt upstream of the cap site to 106 nt downstream of the polyadenylation site showed only the beta 126 GTG----GGG mutation, which was confirmed in the other patients by allele-specific oligonucleotide hybridization. The mutation was found to be associated with a type II beta-globin framework and restriction fragment length polymorphism haplotype V. The novel variant was named hemoglobin Neapolis.

Abstract
A novel 5.3-kb deletion of the alpha-globin gene cluster was observed in a family from Naples, Southern Italy. It removes the 5' end of the alpha 2-globin gene, causing an alpha (+)-thalassemia defect. Because of the presence of the residual 3' end of the alpha 2-globin gene, we indicated this new haplotype with the symbol (alpha)alpha 5.3. The 5' breakpoint, the first to be reported in the intergene region of the psi alpha 2- and psi alpha 1-globin genes, is located 822 bp upstream of the cap site of the psi alpha 1-gene and about 150 bp upstream of a 300-nt Alu family member. The 3' breakpoint is located in the IVS-1 nt 58 of the alpha 2-globin gene. The 5.3-kb deleted fragment shows particular characteristics: it contains four Alu sequences having long regions 80% complementary and the 5'-GGCC-3' short repeat at both ends. The sequences spanning across the breakpoints on the same strand and containing this repeat on their 3' and 5' ends, respectively, are 17 of 25 base complementary. These particular features led us to assume the formation of a multistem-loop due to the intrastrand interaction between the complementary regions as intermediate to the deletion. The unusual localization of the 5' breakpoint suggests that even the intergene region of the psi alpha 2- and psi alpha 1-globin genes may function as a deletion target.

Abstract
In order to evaluate the feasibility of first trimester prenatal diagnosis of beta-thalassaemia by restriction fragment length polymorphism (RFLP) in Campania, one of the most affected regions in Southern Italy, DNA polymorphism analysis was performed on 40 unrelated patients, affected with homozygous beta-thalassaemia, and on their parents. Frequency of the presence of the Hinc II epsilon, Hind III G gamma and A gamma, Hinc II psi beta and 3' psi beta, Ava II psi beta, Ava II beta and Bam HI 3' beta sites have been determined in the beta A and beta thal chromosome samples. In 31 families (over 75%), RFLPs enabled tracing the beta-thalassaemia mutations in both father and mother (100% diagnosis). In the remaining nine families, RFLPs enabled tracing only one of the two mutations (50% diagnosis) because the other parent was found to be homozygous in all the analysed polymorphic sites. Restriction haplotypes, assembled on the basis of linkage analysis, were most heterogeneous, hence a wide heterogeneity of mutations is expected.

Abstract
A procedure using fast atom bombardment mass spectrometry was developed for mapping the proteolytic digest of proteins. The procedure was successfully applied to the tryptic peptides of the human beta-globin chain. Almost all the expected peptides were identified by direct analysis of the peptide mixture on the mass spectrometer. Peptide recognition along the beta-globin chain sequence was easily made on the basis of their molecular weight. The general applicability of this mapping procedure in the analysis of haemoglobinopathies was demonstrated by its use for the structural characterization of a variant beta-globin chain.

Abstract
A case of XXXXY syndrome in a 15 year old male is reported. Clinical findings (mental retardation, muscular hypotonia, hypogonadism, characteristic facies), chromosome analyses as well as fingerprint ridge counts were typical of the syndrome. Several radiological abnormalities were found. It is noteworthy that features consistent with epiphysial dysplasia were present. In the patient's kindred a case of "cri du chat" syndrome and a 5:9 balanced translocation were discovered.

Abstract
It is rare for hereditary forms of primary protrusio acetabuli to be reported, and the mode of transmission is not always clear. The writers present a familial occurrence of this malformation in which the hereditary factor was in accord with the presence of a dominant autosomal gene.

Abstract
Two cases of previously unreported simultaneous presence of A and B postaxial polydactyly in two brothers out of 12 affected members of a kindred are reported. The findings are consistent with the hypothesis that in this family A and b types of postaxial polydactyly are caused by a single gene rather than by two different genes.
