During a 3-year period we studied 393 adult patients (382 of whom were unrelated) with a history of acute venous thromboembolism. A congenital deficiency state known to predispose to thrombosis was found in 27.2%. Of these, most were due to deficiencies of protein C (9.2%), protein S (7.6%), antithrombin III (5%) or to increased plasma PAI-1 concentration (3.1%) which, in the absence of any known factor that predisposes towards thrombosis, results in a diminished fibrinolytic activity. There was a characteristic pattern between the age of onset (mean 34 years) of thrombosis and individual protein deficiency. Thrombosis appeared spontaneously in 73% of cases with recurrence in 80%. In contrast, in the remaining unrelated patients, 138 (35.1%) in whom venous thromboembolism was secondary and occurred at a mean age of 43 years, and in the other 140 (35.6%) who suffered thromboembolism spontaneously at a later age (mean age 55), there was no permanent protein deficiency state or alteration in fibrinolytic activity and thrombosis recurrence was lower (53.6% and 20.7% respectively). Of the 393 patients, deep vein thrombosis was the most common manifestation; however, in congenital thrombophilia, thrombosis of visceral vessels and Raynaud's syndrome (6%) were also detected.

Deep venous thrombosis (DVT) remains a serious clinical problem that affects millions of people worldwide. Some DVT cases are caused by inherited thrombophilia derived from genetic aberrations and several disease-causing genes have been identified so far. Among them, HRG is an uncommon one with limited related reports. Here, we reported on a family with early-onset DVT where acquired risky conditions were excluded. Whole exome sequencing revealed a novel heterozygous single base pair substitution in exon 2 of HRG gene resulting in a conserved residue replacement of the protein (c. C271T, p. P73S). Sanger sequencing confirmed the co-segregation of the mutation and plasma quantification determined circulating protein deficiency. The mutation might therefore impair hemostatic balance by causing reduced circulating HRG level. Our study broadens the mutation spectrum of the HRG gene and underscores the importance of its function in regulating coagulation pathway.
