Introduction: STAT3 orchestrates crucial immune responses through its pleiotropic functions as a transcription factor. Patients with germline monoallelic dominant negative or hypermorphic STAT3 variants, who present with immunodeficiency and/or immune dysregulation, have revealed the importance of balanced STAT3 signaling in lymphocyte differentiation and function, and immune homeostasis. Here, we report a novel missense variant of unknown significance in the DNA binding domain of STAT3 in a patient who experienced hypogammaglobulinemia, lymphadenopathy, hepatosplenomegaly, immune thrombocytopenia, eczema and enteropathy over a 35-year period.

E3 ubiquitin ligases have been linked to developmental diseases including autism, Angelman syndrome (UBE3A), and Johanson-Blizzard syndrome (JBS) (UBR1). Here, we report variants in the E3 ligase UBR5 in 29 individuals presenting with a neurodevelopmental syndrome that includes developmental delay, autism, intellectual disability, epilepsy, movement disorders, and/or genital anomalies. Their phenotype is distinct from JBS due to the absence of exocrine pancreatic insufficiency and the presence of autism, epilepsy, and, in some probands, a movement disorder.

In line with the spirit of the Giens workshops, this article reports on the recommended evolution of the Ethics Committees (CPPs) and the Committees for Research Ethics (CER) in France. These committees play a crucial role in the ethical evaluation of clinical research projects, a process that has become more complex, particularly in view of recent legislative, regulatory and methodological developments. This reflection highlights the current challenges faced by the CPPs, including the increasing workload, the complexity of the issues to be addressed and the need for better use of their resources.
