• Integrated diagnosis based on transcriptome analysis in suspected pediatric sarcomas

  We performed RNA-sequencing in 47 patients with suspected pediatric sarcomas, to evaluate the potential utility of RNA-seq in the diagnostic process of pediatric sarcoma.

• Dnase1l3 deletion causes aberrations in length and end-motif frequencies in plasma DNA

  We showed that mice in which Dnase1l3 had been deleted showed aberrations in the fragmentation of plasma DNA. We also observed a change in the ranked frequencies of end motifs of plasma DNA caused by the Dnase1l3 deletion.

• Nasal Polyp Whole-transcriptome sequencing

  Whole-transcriptome sequencing (RNAseq) in patients with chronic rhinosinusitis with nasal polyps (CRSwNP) and controls. Differential expression patterns in genes involved in cilia, viral defense and NKT-cell specific pathways, suggesting a role of viral immunity in combination with cilia functionality in CRSwNP.

• Heritable pulmonary arterial hypertension - new genetic findings and environmental triggers

  Whole exome seqeuncing data were analysed for a total of 13 family members of five heritable pulmonary arterial hypertension (HPAH) families to identify a disease causing variant. In a first step, variants only present in affected family members and absent in healthy relatives of the respective family were selected. Subseqeuntly, due to incomplete penetrance of genes in PAH, the analysis was extended to variants present both in affected and healthy individuals. Heterozygous variants were primarily investigated followed by homozygous, compound heterozygous, and bi-allelic variants of interest. This study led to the identification of rare deleterious variants in three out of five families.

• A GWAS in uveal melanoma identifies risk polymorphisms in the CLPTM1L locus.

  Uveal melanoma, a rare malignant tumor of the eye, is predominantly observed in populations of European ancestry. A genome-wide association study of 259 uveal melanoma patients compared to 401 controls all of European ancestry revealed a candidate locus at chromosome 5p15.33 (region rs421284: OR = 1.7, CI 1.43-2.05). This locus was replicated in an independent set of 276 cases and 184 controls. In addition, risk variants from this region were positively associated with higher expression of CLPTM1L. In conclusion, the CLPTM1L region contains risk alleles for uveal melanoma susceptibility, suggesting that CLPTM1L could play a role in uveal melanoma oncogenesis.

• Metabolic context regulates the competitive fitness of oncogenic PIK3CA mutant clones in the normal esophagus

  Activating mutations in PIK3CA generate large clones in the aging human esophagus. Here we investigate the underlying cellular mechanisms regulating their expansion by lineage tracing. Expression of an activating heterozygous Pik3caH1047R mutation in single progenitor cells of the mouse esophagus tilts cell fate towards proliferation, generating mutant clones that outcompete their wild type neighbours. The mutation leads to increased aerobic glycolysis through the activation of Hif1α transcriptional targets. In vitro and in vivo interventions that level out differences in activation of the PI3K/HIF1α/aerobic glycolysis axis between wild type and Pik3caH1047R cells attenuate the competitive advantage of the mutants. In contrast, metabolic conditions that alter Insulin/PI3K signalling, such as type-1 diabetes or diet-induced insulin resistance, further increase Pik3caH1047R mutant competitiveness in mice. Consistently, the density of activating PIK3CA mutations in human esophagus is increased in overweight individuals. We conclude that the metabolic environment influences the mutational landscape of normal epithelia. Clinically feasible interventions that even out signalling imbalances between wild type and mutant cells may therefore limit the expansion of oncogenic mutants in normal tissues.

• Mobile Technology to Identify Mechanisms Linking Genetic Variation and Depression in Intern Health Study (IHS)

  The Intern Health Study is an NIH-funded longitudinal cohort study that assesses stress and mood in medical interns at institutions around the US, enrolling over 3000 new interns each year. We are hopeful that data collected in this study will further understanding of the psychological, genetic, and program factors involved in the development of depression under stress, and make a real change in the residency experience.

• The MALT1 Locus and Peanut Avoidance in the Risk for Peanut Allergy

  The LEAP study was a randomized controlled clinical trial in children at increased risk for peanut allergy, in which intervention using dietary introduction of peanut protein beginning in the first 4 to 11 months of life, continued until age 5 years, significantly decreased the frequency of peanut allergy later in childhood and modulated the immune response to peanuts. All subject phenotype data will be hosted on ITN Trial Share under the LEAP study.

• Low T cell diversity is associated with poor outcome in bladder cancer - Single cell RNAseq and TCRseq data

  T cells are crucial effector cells in the endogenous defense against cancer, yet the clinical impact of their quantity, diversity, and dynamics remains underexplored. In this study we performed single cell RNAseq paired with single cell TCR-seq on tumor and blood samples from 4 patients (n samples = 8). The goal was to investigate T cell subtypes of expanded and non-expanded T cell clones in blood and in tumors.

• Immune control of functional memory CD8 T cells in normal-appearing vitiligo skin

  This study aimed to characterize immune cell states in nonlesional (NL) and perilesional (PL) skin of patients with vitiligo using single-cell RNA sequencing. Shared CD8⁺ T cell clusters were detected in both regions, with PL-derived cells enriched for immune activation pathways and NL skin showed stronger infiltration of regulatory T cells. These findings reveal functional T cell heterogeneity in vitiligo and highlight regulatory mechanisms that may limit depigmentation in NL skin.
