Filter by:This non-drug, longitudinal, multi-center, multi-national study will evaluate the suitability of neurocognitive tests and functioning scales for the measurement of cognitive and functioning changes in individuals with Down Syndrome. Tests will be administered at clinic visits in Weeks 1, (4) and 24. The duration of the study for each individual will be between 24 and 27 weeks.
Evaluation of the following in very young children with Down syndrome: - the efficacy of systematic treatment with L-thyroxine at controlled doses (clinically and by ultrasensitive thyreostimulating hormone (TSH) assay), - the efficacy of systematic folinic acid treatment at a dose of 1 mg/kg/o.i.d, - any interaction between these two treatments.
Whole blood samples will be collected from high-risk pregnant women to validate the clinical performance of the SEQureDx Trisomy 21 Test.
This prospective blinded study will assess the diagnostic capability of an informatics enhanced SNP based technology (Parental Support) to identify pregnant women who are carrying a fetus with an aneuploidy from fee floating DNA in the maternal blood.
RATIONALE: Studying samples of blood, tissue, and bone marrow from patients with cancer in the laboratory may help doctors learn about changes that occur in RNA and identify biomarkers related to cancer. PURPOSE: This research trial studies RNA samples from patients with Down syndrome and acute myeloid leukemia or other transient myeloproliferative disorder.
The purpose of this blinded, multi-center, prospective, case-controlled study is to compare the Ariosa Harmony™ Prenatal Test for trisomy 21 detection with a standard first-trimester prenatal screening test consisting of serum screening (PAPP-A,free beta-hCG [β-hCG] or total hCG) and a nuchal translucency (NT) measurement (i.e. combined first trimester screening) in a general screened population. The performance characteristics of these two test modalities will be assessed relative to the clinical reference standard of genetic analysis of the fetus or phenotypic characterization and genetic analysis of the newborn.
RATIONALE: Studying samples of blood, tissue, and bone marrow from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research trial studies DNA samples from patients with Down syndrome and acute myeloid leukemia treated on COG-AAML0431 clinical trial.
This multi-center, randomized double-blind, placebo-controlled study will assess the safety and tolerability of RG1662 in individuals with Down Syndrome. Eligible subjects will be randomized in cohorts to receive either multiple oral doses of RG1662 or placebo. Anticipated time on study treatment is 38 days.
The specimen collection is designed for the purpose of the development of a noninvasive prenatal test for T21.
There is a mounting evidence of the modulation properties of the major catechin in green tea, epigallocatechin-3-gallate (EGCG), on dual specificity tyrosine-phosphorylation-regulated kinase 1A (DYRK1A) gene overexpression in the brains of DS mouse models.The aims are to investigate the clinical benefits and safety of EGCG administration in young adults with DS, to establish short-term EGCG effects (three months) on neurocognitive performance, and to determine the persistency or reversibility of EGCG related effects after three months of discontinued use.
