| Variant | L265P |

| Recommended combinations | ibrutinib (off-label R/R MZL), zanubrutinib (FDA-approved R/R MZL — not MYD88-selected) |
| Evidence summary | MYD88 L265P found in ~5-10% of MZL (more in lymphoplasmacytoid variants; rare in classic SMZL/NMZL). Suggests overlap with WM biology and supports BTKi consideration in R/R disease (off-label). |
Notes
ESCAT IIIA. Zanubrutinib has tissue-agnostic MZL approval (MAGNOLIA) regardless of MYD88 status.
