TL;DR
An elderly woman with severe chronic neutropenia caused by mosaic TLR8 gain-of-function is described, which broadens a primarily pediatric, male disease spectrum and highlights somatic mosaicism as an important diagnostic consideration in adults with unexplained cytopenia and immune dysregulation.
Abstract
Patel et al. describe an elderly woman with severe chronic neutropenia caused by mosaic TLR8 gain-of-function. The report broadens a primarily pediatric, male disease spectrum and highlights somatic mosaicism as an important diagnostic consideration in adults with unexplained cytopenia and immune dysregulation.
In this Review, Gil and Cooper review the molecular, immunologic, and clinical features of TLR8 gain-of-function syndrome. They review findings from patients with mosaic and germline disease, and integrate knowledge of key structural components of the TLR8 protein.

Iglesias-Herrero et al. longitudinally assess JAK-inhibitor treatment response in two patients with STAT1 gain-of-function and show that it induces rapid but incomplete immune reconstitution, with increased TCR diversity and reversal of monocyte hyperinflammation, highlighting both therapeutic benefit and persistent im...

An 81-year-old woman receiving upadacitinib, a JAK-1 inhibitor, for rheumatoid arthritis developed herpes zoster ophthalmicus with significant ophthalmic morbidity and varicella-zoster virus encephalitis. Medication reconciliation revealed continued JAK-1 inhibition during early presentations. This case highlights the...

An 82‐year‐old woman with JAK2‐mutated myelofibrosis who developed hemoptysis after initiation of ruxolitinib. She presented with anemia and ground‐glass opacities and was treated with antibiotics. She was readmitted with worsening respiratory symptoms. Sputum cultures yielded Mycobacterium avium. Her clinical course w...
