Among antibodies, patients with DVT and those without DVT did not differ for ANA (p = 0.916), and antibodies directed against dsDNA (p = 0.139), nucleosomes (p = 0.213), histones (p = 0.058), beta-2-glycoprotein IgG (p = 0.572), beta-2-glycoprotein IgM (p = 0.614), cardiolipin IgG (p = 0.837), and cardiolipin IgM (p = 0.884). This evidence concerns the gene BTG3 and deep vein thrombosis.
