Molecular cytogenetic characterisation of a mosaic add(12)(p13.3) with an inv dup(3)(q26.31 --> qter) detected in an autistic boy

BACKGROUND: Inverted duplications (inv dup) of a terminal chromosome region are a particular subset of rearrangements that often results in partial tetrasomy or partial trisomy when accompanied by a deleted chromosome. Associated mosaicism could be the consequence of a post-zygotic event or could result from the correction of a trisomic conception. Tetrasomies of distal segments of the chromosome 3q are rare genetic events and their phenotypic manifestations are diverse. To our knowledge, there are only 12 cases reported with partial 3q tetrasomy. Generally, individuals with this genomic imbalance present mild to severe developmental delay, facial dysmorphisms and skin pigmentary disorders. RESULTS: We present the results of the molecular cytogenetic characterization of an unbalanced mosaic karyotype consisting of mos 46,XY,add(12)(p13.3) [56]/46,XY [44] in a previously described 11 years old autistic boy, re-evaluated at adult age. The employment of fluorescence in situ hybridization (FISH) and multicolor banding (MCB) techniques identified the extra material on 12p to be derived from chromosome 3, defining the additional material on 12p as an inv dup(3)(qter --> q26.3::q26.3 --> qter). Subsequently, array-based comparative genomic hybridization (aCGH) confirmed the breakpoint at 3q26.31, defining the extra material with a length of 24.92 Mb to be between 174.37 and 199.29 Mb. CONCLUSION: This is the thirteenth reported case of inversion-duplication 3q, being the first one described as an inv dup translocated onto a non-homologous chromosome. The mosaic terminal inv dup(3q) observed could be the result of two proposed alternative mechanisms. The most striking feature of this case is the autistic behavior of the proband, a characteristic not shared by any other patient with tetrasomy for 3q26.31 --> 3qter. The present work further illustrates the advantages of the use of an integrative cytogenetic strategy, composed both by conventional and molecular techniques, on providing powerful information for an accurate diagnosis. This report also highlights a chromosome region potentially involved in autistic disorders

INFLUENCE OF THERAPY UPON LPS-INDUCED CYTOKINE SECRETION BY THE BLOOD-DERIVED INNATE IMMUNITY CELLS OF THE BRONCHIAL ASTHMA PATIENTS

Bronchial asthma (BA) is the most widespread chronic inflammatory disease. Since BA is associated with a systemic inflammation state, a comprehensive study of its effect in this disease, and influence of pathogenetic therapy should be performed, by studying the whole blood cytokine status of the patients suffering with BA. The cells from respiratory tract in acute-phase BA patients may produce pro-, as well as anti-inflammatory mediators. The anti-inflammatory mediators are able to suppress activity of immune cells in peripheral blood. Thus, the aim of present study was to evaluate eventual inflammation-associated and functional activity of immune cells from the patients’ peripheral blood in BA and following appropriate therapy. Bacterial lipopolysaccharide (LPS) a classical pro-inflammatory agent. We have studied an LPSinduced cytokine-induced ex vivo secretion model by peripheral blood immune cells, as a relevant test for their functional activity. The LPS-induced responses of whole blood cells from patients with proven BA diagnosis have been studied at pre-treatment time points, and following two weeks of basic anti-inflammatory therapy. According to clinical indications, the antagonists of CysLTR1, or combinations of glucocorticosteroids and β-adrenoreceptor agonists were administered by inhalation to BA patients. LPS-induced production of TNFα, IL-6, IL-8 (at 6 h) and IFNγ, IL-17A or IL-1β (at 24 h) by whole blood cells from BA patients or healthy volunteers has been assessed by ELISA technique. The cytokine production from non-stimulated whole blood cells from BA patients and healthy volunteers were used as the baseline control. IL-4 concentrations in plasma of BA patients and healthy volunteers were also measured. We have shown a decrease of IL-6 production in control blood samples from BA patients after two weeks of therapy. This may indicate the attenuation of the observed inflammatory process. The therapy applied did not influence the background levels and LPS-induced secretion of IL-1β, IL-1ra, IFNγ, and IL-8 in whole blood samples from BA patients. IL-4 plasma levels in BA patients were not changed after two weeks of therapy. It has been shown that whole blood from BA patients produced less TNFα and IL-8, both in control samples, and during their response to LPS, than the values obtained in healthy volunteers. These findings are in agreement with a notion that BA causes partial depression of innate immune cells activity. The increased LPS-induced TNFα secretion by the whole blood cells from BA patients has been observed following two weeks of basic anti-inflammatory therapy. We suggest that the increased LPS-induced TNFα secretion could be explained by partial restoration of peripheral blood immune cell activity associated with anti-inflammatory BA therapy. To elucidate the mechanism of increased LPS-induced TNFα secretion, we have estimated whole blood concentration of soluble CD14 (sCD14) in BA patients. No significant differences between sCD14 concentrations have been found. Obtained result presume existence of sCD14-independent mechanism of TNFα regulation by whole blood cells in response on LPS which may occur during anti-inflammatory therapy of BA. We suppose that basic anti-inflammatory therapy of BA does not simply reduce IL-6 concentration in peripheral blood, but may also partially restore the activity of innate immune cells in BA patients

Characterization of a prenatally assessed de novo supernumerary minute ring chromosome 20 in a phenotypically normal male

<p>Abstract</p> <p>Background</p> <p>The heterogeneous group of small supernumerary marker chromosomes (sSMCs) presents serious counseling problems, especially if they are present de novo and diagnosed prenatally. The incidence has been estimated at 1 in 1000 prenatal samples. We present a case of mosaic sSMC diagnosed prenatally after amniocentesis. The sSMC was characterized by various molecular cytogenetic techniques and determined to be a r(20) chromosome. After genetic counseling, the parents decided to continue the pregnancy, and a boy with minor phenotypic variants was born after 39 weeks of pregnancy. The case is compared with four other cases of prenatally detected r(20) mosaicism.</p> <p>Results</p> <p>Here we describe a 3 months old male child with normal pre- and postnatal development and with a de novo ring supernumerary marker chromosome in amniocytes cultures. Using new fluorescence in situ hybridization (FISH) techniques, three distinguishable sSMCs (cryptic mosaicism), all derived from chromosome 20, were observed, including ring and minute chromosomes. This heterogeneity was impossible to detect by the conventional G-banding technique or conventional FISH technique that were used before the application of new FISH techniques (subcentromere-specific multicolor-FISH [subcenM-FISH]) and a probe, specific for the 20p12.2 band. The sSMC present in 25% of the cells was present as r(20)(::p12.2~12.3->q11.1::)<abbrgrp><abbr bid="B5">5</abbr></abbrgrp>/r(20;20)(::p12.1->q11.1::q11.1 >p12.1::)<abbrgrp><abbr bid="B2">2</abbr></abbrgrp>/min(20;20)(:p12.1->q11.1::q11.1->p12.1:)<abbrgrp><abbr bid="B1">1</abbr></abbrgrp>. The final karyotype was 47,XY,+r(20)[25%]/46,XY[75%].</p> <p>Conclusion</p> <p>We emphasize the importance of application of molecular cytogenetics in a prenatally diagnostic laboratory and description of more cases to enable a better genetic counseling and risk evaluation.</p

Contribution of chromosomal abnormalities and genes of the major histocompatibility complex to early pregnancy losses

Aim. The determination of chromosomal abnormalities in samples from early pregnancy losses and allelic polymorphism of HLA–DRB1 and DQA1 genes in couples with recurrent miscarriage. Methods. Banding cytogenetic and interphase mFISH analysis, DNA extraction by salting method, PCR, agarose gel electrophoresis. Results. Cytogenetic and molecular-cytogenetic investigations of SA material identified karyotype anomalies in 32.4 % of cases with prevalence of autosomal trisomy – 42.65 %, triploidy – 30.38 % and monosomy X – 19.11 %. Complex analysis of frequency and distribution of allelic variants of genes HLA-DRB1 and HLA-DQA1 allowed establishing the alleles DRB1*0301, DRB1*1101-1104 and DQA1*0501 to be aggressor alleles in women with recurrent pregnancy loss (RPL). The cumulative homology of allelic polymorphism of more than 50 % of HLA-DRB1 and HLA-DQA1 loci between partners increases the risk of RPL by almost four times. Conclusion. The detected chromosome aneuploidies in the samples from products of conception and the changes in the major histocompatibility complex genes can cause the failure of a couples reproductive function and can lead to an early fetal loss.Мета.

Роль герпес-вирусной инфекции при болезни (синдроме) Шегрена

The etiology of Sjц gren's disease (syndrome) - SD, SS - is unknown; however, its frequent development in patients with hepatitis B or C or AIDS in infection with human lymphotropic virus type (HLTV-1) suggests the viral nature of the disease. A large body of data available in the literature shows the promise of studying the implication of viral infection in the development of SD and SS, at the early stages of the development in particular.Этиология болезни (синдрома) Шегрена (БШ,СШ) неизвестна, однако частое ее развитие у больных гепатитом В, С, СПИДом при инфицированности человеческим лимфотропным вирусом 1-го типа (HLTV 1) предполагает вирусную природу болезни. Многочисленные данные литературы свидетельствуют о перспективности изучения роли вирусной инфекции в развитии БШ и СШ, особенно на ранних стадиях заболевания
