Somatic Mutation

Somatic mosaicism in cancer associated genes is one potential explanation for discordance in childhood cancer that has not been fully explored to date. This pilot study will focus on twins with central nervous system (CNS) tumors who are identified through the Children's Oncology Group's Project: EveryChild (PEC) registry or volunteer.

This is a phase II, open-label, prospective study of T cell receptor alpha/beta depletion (TCR α/β TCD) peripheral blood stem cell (PBSC) transplantation for children and adults with hematological malignancies. This is a safety/feasibility study of the investigational procedure/product.

The goal of this study is to This research team is conducting this study to develop methods to measure the biological impact of exposure to the chemicals released following the February 3, 2023 train derailment on residents of East Palestine, Ohio, and surrounding communities. The main question it aims to answer is: * What biological impact will be measured based on DNA damage? * In participants who provide a biospecimen, how are biomarker changes related to proximity to the derailment and variations in residents' health histories and behaviors? Participants will: * Complete a brief survey asking about experiences related to the February 3, 2023 train derailment, health experiences, and concerns following the derailment, and background information regarding health history. * Possibly contribute biospecimens such as blood, spit, hair, and/or toenail clippings. * Receive communication about study updates and future research opportunities. * A total of 40 study participants will be recruited to participate in a 90-minute interview. The interviews will be video and audio recorded.

Systemic autoinflammatory diseases (SAIDs) are a set of rare clinically and genetically heterogeneous conditions. The project proposes to identify novel genes and specific signatures in subgroups of patients with SAIDs.

For patients of advanced NSCLC (non small cell lung cancer) , Individualized cancer therapy has been widely accepted since the success of crizotinib administration based on EML4-ALK fusion gene detection and gefitinib and erlotinib administration based on EGFR-TKIs sensitive mutations.From clinical points of view ,individual differences often occur between different patients, leading diverse effect in ADR and drug effect.Meanwhile ,the drug effect and adverse drug reaction was significantly influenced by the pharmacokinetic factors and pharmacodynamic factors.In this research ,we try to establish a more sensitive method to detect sensitive mutations in plasma and discover the correlation between somatic and germline mutations , trough concentration and EGFR-TKI drug effect, the association between ADME-associated SNP ,trough concentration and EGFR-TKI adverse effect .Furthermore, in vivo and in vitro research is also crucial for rational explanation for these clinical phenomenon.

Phaeochromocytomas and paragangliomas (PPGLs) are tumours of the adrenal medulla and extra-adrenal sympathetic nervous system, some which can become metastatic. It is a very rare disease and the tumours are often detected late. Approximately 50 % of the tumours are caused by germline genetic variants screening programmes are recommended for patients and their family members; however, they are not yet well-targeted with respect to individual prognosis. In this study the investigatorscaim to characterize the genotype-phenotype associations in all Danish patients (n=400) diagnosed with PPGLs who have been followed in tertiary centres using medical records and national registries. To this end novel immunohistochemical, genetic, and epigenetic biomarkers in tumour tissues samples from biobank material (blood samples and tumour tissue) will be investigated to develop a comprehensive predictive algorithm for disease prognosis. The study will provide a clinical tool for an improved targeted screening program and subsequently prevention of disease development.
