The HABP2 G534E polymorphism does not increase nonmedullary thyroid cancer risk in Hispanics. [PDF]

, 2016
Familial nonmedullary thyroid cancer (NMTC) has not been clearly linked to causal germline variants, despite the large role that genetic factors play in risk. Recently, HABP2 G534E (rs7080536A) has been implicated as a causal variant in NMTC.

Unveiling relative lymphopenia and elevated monocyte‐to‐lymphocyte count as novel independent adverse prognostic factors in chronic myelomonocytic leukemia (CMML)—Proposal of the objective prognostic index for CMML (OPIC)

HemaSphere, Volume 10, Issue 1, January 2026.
Abstract Chronic myelomonocytic leukemia (CMML) shows marked prognostic heterogeneity. Although leukocytosis is a recognized adverse prognostic factor, the contribution of its individual components remains insufficiently defined.
