People with Down syndrome (DS) are at high risk of developing pathology similar to Alzheimer's disease (AD). Modeling of this pathology in vitro may be useful for studying this phenomenon. In this study, we analyzed three different cultures of neural cells carrying trisomy of chromosome 21, which were generated by directed differentiation from induced pluripotent stem cells (iPS cells). We report here that in vitro generated DS neural cells have abnormal metabolism of amyloid-β (Aβ) manifested by increased secretion and accumulation of Aβ granules of Aβ42 pathological isoform with upregulated expression of the APP gene...

Trisomy 8 (+8) is one of the most common cytogenetic abnormalities in adult patients with acute myeloid leukemia (AML). However, the outcome of allogeneic hematopoietic stem cell transplantation (HSCT) in adult patients with AML harboring +8 remains unclear. To evaluate, the outcome and prognostic factors in patients with AML harboring +8 as the only chromosomal abnormality or in association with other abnormalities, we retrospectively analyzed the Japanese registration data of 631 adult patients with AML harboring +8 treated with allogeneic HSCT between 1990 and 2013...

: We present a patient with poikiloderma, severe osteoporosis and a mild intellectual disability. At the age of 9 years, this patient was proposed to suffer from a novel disease entity designated as calcinosis cutis, osteoma cutis, poikiloderma and skeletal abnormalities (COPS) syndrome. At the age of 35, he was diagnosed with Hodgkin's lymphoma. Recently, biallelic pathogenic variants in the RECQL4 gene were detected (c.1048_1049delAG and c.1391-1G>A), confirming a diagnosis of Rothmund-Thomson syndrome (RTS)...

Maternal uniparental disomy of chromosome 16 (upd(16)mat) as the result of trisomy 16 is one of the most frequently reported uniparental disomies in humans, but a consistent phenotype is not obvious. Particularly, it is difficult to discriminate between features resulting from upd(16)mat and mosaic trisomy 16. By evaluating literature data (n = 74) and three own cases we aimed to determine whether the clinical features are due to upd(16)mat or to trisomy 16 mosaicism. Whereas in single cases the clinical symptoms were caused by homozygosity of autosomal recessive mutations on chromosome 16, it turned out that clinical features in upd(16)mat are caused by (hidden) trisomy 16 mosaicism and a specific chromosome 16 associated imprinting disorder does not exist...

Down syndrome (also known as trisomy 21) is the model human phenotype for all genomic gain dosage imbalances, including microduplications. The functional genomic exploration of the post-sequencing years of chromosome 21, and the generation of numerous cellular and mouse models, have provided an unprecedented opportunity to decipher the molecular consequences of genome dosage imbalance. Studies of Down syndrome could provide knowledge far beyond the well-known characteristics of intellectual disability and dysmorphic features, as several other important features, including congenital heart defects, early ageing, Alzheimer disease and childhood leukaemia, are also part of the Down syndrome phenotypic spectrum...

OBJECTIVES: Down syndrome (DS)-associated transient abnormal myelopoiesis (TAM) or acute megakaryoblastic leukemia (AMKL) in monozygotic twins is exceedingly rare and has not been well characterized. METHODS: We describe a unique case of monozygotic twins with simultaneous TAM from a triplet pregnancy at 34 weeks' gestation. Previously reported cases of TAM and DS-AMKL in monozygotic twins have been reviewed to compare with our cases. The current concept of a sequential multistep process in leukemogenesis and disease evolution of TAM into DS-AMKL through the collaboration among trisomy 21, GATA1, and other gene mutations is also reviewed...

The objective of this work is to introduce a noninvasive diagnosis procedure for aneuploidy and minimize the social and financial cost of prenatal diagnosis tests that are performed for fetal aneuploidies in an early stage of pregnancy. We propose a method using artificial neural networks trained with data from singleton pregnancy cases, while undergoing first trimester screening. Three different datasets1 with a total of 122362 euploid and 967 aneuploid cases were used in this study. The data for each case contained markers collected from the mother and the fetus...

We aimed to identify key genes located on chromosome 21 as potential biomarkers for prenatal diagnosis of trisomy 21 (Ts21). The microarray data of GSE48051, including 10 cultivated amniocyte samples with Ts21 and 9 controls with normal euploid constitution, was obtained from Gene Expression Omnibus database. The differentially expressed genes (DEGs) in cultivated amniocyte samples with Ts21 compared to normal controls were screened using limma package. Then, we performed GO enrichment analysis using DAVID and chromosomal location of DEGs based on the information of the University of California Santa Cruz (UCSC) Genome Browser Database...
