    Severe Systemic Auto-Inflammation in an Elderly Woman with Clonal Hematopoiesis (AMP Europe 2023)
    The discovery of clonal hematopoiesis in this elderly woman with a wide spectrum of severe auto-inflammatory conditions supports a potentially intriguing link between somatic blood mutations and her adult- onset rheumatologic disorders. Mechanistically, disrupted SRSF2-mediated splicing may be driving aberrant antigen presentation by bone marrow-derived dendritic cells in her skin and other organs. Causal relationships between somatic blood mutations and autoimmune/auto-inflammatory conditions have been established in patients with hematologic malignancies and conditions like VEXAS syndrome.

    [VIRTUAL] Mutation Detection in Circulating Tumor Cells at the SingleCell Level Using the MassARRAY System (AMP 2021)
    We have established a novel, straightforward protocol to detect mutation directly from CTC without preamplification at the single cell level. We expect that this workflow will facilitate the exploration of genetic content of CTC, thereby increasing its potential use in the clinic

    Novel Recurrent Mutations in Eldheim-Chester Disease Patients Identified By Whole Exome Sequencing and Whole Genome Sequencing (ASH 2021)
    In addition, we revealed heterogeneity of mutational profile of multi lesions in an ECD patient with BRAF V600E mutation. It is noteworthy that mutational profiles might be different depending on the organ of the lesion.
