The analysis of the correlation between SAMD1 and different clinicopathological characteristics of APS patients showed that SAMD1 expression in the peripheral blood serum of APS patients was correlated with the history of thrombosis and the number of adverse pregnancy deliveries, but not with the patient's age, body mass index, and the number of pregnancies (Table 2). Here, SAMD1 is linked to deep vein thrombosis.
