Comparing the results of the meta-analysis described above (8) with the results of previous APS studies (9, 10), we found that the genes ANXA3, TNFAIP6, TXK, BACH2, and SERPINB2 are differentially expressed in both venous and arterial thrombosis as well as in APS compared to healthy subjects. Here, BACH2 is linked to Arterial thrombosis.
