However, when assessing its association with chemotherapy, there was a significant reduction in ADAMTS-13 from baseline in those who developed DVT (delta value − 0.27 with DVT vs. + 0.05, p = 0.015), while nearly all patients showed slightly increased vWF:Ag (delta value + 0.27 vs. + 0.21, p = 0.379) over time. The gene discussed is ADAMTS13; the disease is deep vein thrombosis.
