Patients heterozygous for germline CBL loss-of-function (LOF) variants can develop myeloid malignancy, autoinflammation, or both, if some or all of their leukocytes become homozygous for these variants through somatic loss of heterozygosity (LOH) via uniparental isodisomy. We observed an upregulation of the inflammatory gene expression signature in whole blood from these patients, mimicking monogenic inborn errors underlying autoinflammation. Remarkably, these patients had constitutively activated monocytes that secreted 10 to 100 times more inflammatory cytokines than those of healthy individuals and CBL LOF heterozygotes without LOH.

- * This deficiency results in the impaired translation of important proteins like JAK2, affecting cellular responses to specific cytokines such as IL-23 and IL-12, particularly in T lymphocytes and phagocytes.
- * The impaired response to IL-23 reduces the production of IFN-γ by certain immune cells during mycobacterial infections, highlighting a crucial link between MCTS1 deficiency and mycobacterial disease susceptibility.
