Initial Clinical Experience with NIPT for Rare Autosomal Aneuploidies and Large Copy Number Variations.

Objective: Amniocentesis, chorionic villi sampling and first trimester combined testing are able to screen for common trisomies 13, 18, and 21 and other atypical chromosomal anomalies (ACA). The most frequent atypical aberrations reported are rare autosomal aneuploidies (RAA) and copy number variations (CNV), which are deletions or duplications of various sizes. We evaluated the clinical outcome of non-invasive prenatal testing (NIPT) results positive for RAA and large CNVs to determine the clinical significance of these abnormal results.

47 patients with FLNA associated periventricular nodular heterotopia.

Background: Heterozygous loss of function mutations within the Filamin A gene in Xq28 are the most frequent cause of bilateral neuronal periventricular nodular heterotopia (PVNH). Most affected females are reported to initially present with difficult to treat seizures at variable age of onset. Psychomotor development and cognition may be normal or mildly to moderately impaired.

Molecular and clinical characterization of an in frame deletion of uncertain clinical significance in the BRCA2 gene.

In this study, we analyzed a "variant of uncertain significance" (VUS) located in exon 23 of the BRCA2 gene exhibited by six members of five distinct families with hereditary breast cancer (BC). The variant was identified by DNA sequencing, and cDNA analysis revealed its co-expression with wild-type mRNA. We analyzed co-occurrence with other pathological mutations in BRCA1/2, performed a case-control study, looked for evolutionary data and used in-silico analyses to predict its potential clinical significance.

Intragenic deletions of IL1RAPL1: Report of two cases and review of the literature.

IL1RAPL1 (interleukin-1 receptor accessory protein-like 1) located at Xp21.3-22.1 has repeatedly been shown to be deleted in patients with a contiguous gene syndrome also affecting neighboring genes, in particular DMD (dystrophin), DAX-1 (NR0B1, nuclear receptor subfamily 0, group B, member 1), and GK (glycerol kinase).

IgE-mediated allergen gene vaccine platform targeting human antigen-presenting cells through the high-affinity IgE receptor.

Background: Treatment of IgE-mediated food allergy with standard protein-based allergen immunotherapy has proved both unsuccessful and hazardous. Allergen gene vaccination represents a promising alternative, but difficulties in gene targeting and expression in antigen-presenting cells represent a major limitation for efficient gene vaccination.

Objective: We sought to construct a genetically engineered human epsilon-polylysine (EPL) fusion protein that binds allergen gene expression systems and targets the gene vaccine complex to antigen-presenting cells through the interaction of EPL and the high-affinity receptor for IgE for efficient allergen gene vaccination.

N-methyl-norsalsolinol modulates serotonin metabolism in the rat caudate nucleus: correlation with behavioural changes.

In earlier studies the dihydroxylated tetrahydroisoquinoline derivative 2(N)-methyl-norsalsolinol (NMNorsal) was identified in patients with Parkinson's disease. In the present study, NMNorsal (20 or 40 mg/kg) was given intraperitoneally to rats kept under normal light-dark cycles. Using brain microdialysis technique, serotonin (5-HT), 5-hydroxyindolacetic acid (HIAA), dopamine (DA), and 3,4-dihydroxyphenylacetic acid (DOPAC) were determined in the dialysate from caudate nucleus in vivo and from tissue in vitro at various times following NMNorsal administration.

N-methyl-norsalsolinol, a putative dopaminergic neurotoxin, passes through the blood-brain barrier in vivo.

In earlier studies the dihydroxylated tetrahydroisoquinoline derivatives salsolinol and 2(N)-methyl-norsalsolinol (NMNorsal), a 2(N)-analogue of salsolinol, were identified as putative endogenous neurotoxins in patients with Parkinson's disease. Since a prominent blood-brain barrier (BBB) was described to exist for salsolinol, in the present study microdialysis experiments were performed to investigate the penetration of NMNorsal through the BBB into the caudate nucleus of the rat brain.
