Hypoplastic left heart syndrome (HLHS) is one of the most severe congenital heart malformations, characterized by underdevelopment of the structures in the left heart-aorta complex. The majority of cases are sporadic. Although multiple genetic loci have been tentatively implicated in HLHS, no gene or pathway seems to be specifically associated with the(More)
Mouse splenic marginal zone precursors (MZPs) differentiate into marginal zone B (MZB) cells under a signaling pathway involving Notch2 and its ligand, delta-like 1 ligand (Dll1). We report the identification of an MZP subset in the spleen of young children. These MZPs differentiate into MZ-like B cells in vitro in the presence of OP9 cells expressing human(More)
The haploinsufficiency of chromosome 22q11.2 can cause both DiGeorge and velocardiofacial syndromes, both of which are characterized by conotruncal heart defects as well as a wide range of other extracardiac anomalies. Several studies have demonstrated that approximately 10-20% of patients with conotruncal heart defects have a 22q11.2 deletion. In clinical(More)
End-stage hypertrophic cardiomyopathy (ES-HC) has an ominous prognosis. Whether genotype can influence ES-HC occurrence is unresolved. We assessed the spectrum and clinical correlates of HC-associated mutations in a large multicenter cohort with end-stage ES-HC. Sequencing analysis of 8 sarcomere genes (MYH7, MYBPC3, TNNI3, TNNT2, TPM1, MYL2, MYL3, and(More)
MOTIVATION Next-generation sequencing (NGS) methods have the potential for changing the landscape of biomedical science, but at the same time pose several problems in analysis and interpretation. Currently, there are many commercial and public software packages that analyze NGS data. However, the limitations of these applications include output which is(More)
In the present paper we evaluate the optimum chemical conditions for labelling atrial natriuretic peptide (ANP) and its metabolites and for preparing highly purified radiotracers which can be used for in vivo kinetic studies of ANP in humans. Synthetic a h1–28ANP and some hormone metabolites were iodinated with Na125I or Na131I by means of the(More)
We describe the case of a 6-year-old boy with a de novo deletion of the long arm of chromosome 1 encompassing band 1q31.1-q32.1, minor facial anomalies, mild developmental delay, and behavioral disorders. His postnatal karyotype was normal. Using array-comparative genomic hybridization, we identified and characterized a de novo 1q interstitial deletion of(More)
Reports related some polymorphisms of the 5,10-methylenetetrahydrofolate reductase (MTHFR) to folate-dependent neural tube defects. In view of the common origin of the cells involved both in neural tube closure and heart septation, we analyzed the MTHFR C677T and A1298C polymorphisms in mothers of children with conotruncal heart defect (CD) and in their(More)
A female newborn was referred at birth to our hospital because of respiratory distress. Her family history was unremarkable except for the first-degree consanguinity of her parents. She had a mildly dysmorphic appearance, generalized hypotonia, and several musculoskeletal features such as joint laxity, arachnodactyly, pectus excavatum, flexion contracture(More)
