Retrospective study explores clinical impact of STAT5B mutations in lymphoid and myeloid neoplasms, suggesting implications for diagnostics.

To investigate the clinical significance and distribution of STAT5B mutations in lymphoid and myeloid malignancies.
Retrospective study of adult patients with lymphoid or myeloid malignancies harboring STAT5B mutations detected by NGS.
Mutations stratified into tiers based on pathogenicity and functional data.
Overall survival and progression-free survival estimated using Kaplan–Meier method.
Out of 76 patients, 50 had pathogenic STAT5B mutations across various malignancies.
The most common mutation was N642H, followed by T628S and V712E, associated with distinct clinical phenotypes.
No significant differences in overall or progression-free survival were observed between mutation tiers.

Walker et al. (2025) studied this question.
