Project description:Epigenomewide methylation profiling of tumor DNA from pediatric germ cell tumors by sex, tumor histology, tumor location and age at diagnosis. DNA methylation was measured using the Illumina Infinium HumanMethylation450 array
Project description:To compare the transcriptome profiles of the two principal histological variants of malignant germ cell tumor that occur in childhood Experiment Overall Design: Here, we analyzed the global gene expression profiles of 27 pediatric MGCTs from the two principal histologies (18 yolk sac tumors [YSTs] and 9 seminomas).
Project description:This SuperSeries is composed of the following subset Series: GSE19347: microRNA expression data from pediatric primary intracranial germ cell tumor GSE19348: expression data from pediatric primary intracranial germ cell tumor GSE19349: Genotyping and analysis of chromosome copy number variation (CNV) from pediatric primary intracranial germ cell tumor Refer to individual Series
Project description:The Investigators will conduct a longitudinal, mixed-methods cohort study to assess primary and secondary psychosocial outcomes among 705 MyCode pediatric participants and their parents, and health behaviors of parents whose children receive an adult- or pediatric-onset genomic result. Data will be gathered via quantitative surveys using validated measures of distress, family functioning, quality of life, body image, perceived cancer/heart disease risk, genetic counseling satisfaction, genomics knowledge, and adjustment to genetic information; qualitative interviews with adolescents and parents; and electronic health records review of parents’ cascade testing uptake and initiation of risk reduction behaviors. The investigators will also conduct empirical and theoretical legal research to examine the loss of chance doctrine and its applicability to genomic research.
Project description:Intracranial pediatric germ cell tumors (GCTs) have different histological differentiations, prognosis and clinical behaviors. Prognosis of patients with germinoma and mature teratoma is good, while patients with other types of GCTs, termed as nongerminomatous malignant germ cell tumors (NGMGCTs), require more extensive drug and irradiation treatment regimen. The mechanisms underlying different prognosis of various GCT subgroups remain elusive. We presented the first miRNA profile of pediatric primary intracranial GCTs.
Project description:This SuperSeries is composed of the following subset Series: GSE24697: Breast tumors from CHEK2 1100delC mutation carriers: genomic landscape and clinical implications (GEX) GSE24698: Breast tumors from CHEK2 1100delC mutation carriers: genomic landscape and clinical implications (CGH) Refer to individual Series
