We evidence the increased risk of venous thromboembolism associated with this cryptic splice-site variant if present in patients with PS deficiency.engProtein S deficiencyThrombosisVenous thromboembolismPROS1 novel splice-site variant decreases protein S expression in patients from two families with thrombotic diseasejournal article10.1002/ccr3.1226
