2 Fig. 1 Sequences provided for genotyping of the 5-HT receptor and transporter variant data in fasta format. The human serotonin 2A receptor gene (5HTR2A) gene variant 1354C>T is highlighted in yellow in A. This is a synonymous SNP translating to the amino acid change His452Tyr. The human serotonin transporter (5-HTT; SLC6A4) gene variant (5-HTTLPR) is depicted in B. This gene carries a 44bp insertion/deletion promoter polymorphism (−1440 to −1396) indicated in red.

3 Fig. 2 Patients with the LL phenotype for the 5-HTT gene have increased serum TXB2 level by 5-HTTLPR genotype. Serum TX (ng/ml) on the y-axis and genotype on the x-axis. Thrombosis Research  , 51-55DOI: ( /j.thromres ) Copyright © 2016 Elsevier Ltd Terms and Conditions

4 Fig. 3 The 5-HTTLPR genotype is associated with TXB2 levels >2.2ng/ml. Patients with elevated serum TXB2 levels (TX>2.2ng/ml) are indicated in blue. Numbers of patients on the y-axis and genotype on the x-axis. Thrombosis Research  , 51-55DOI: ( /j.thromres ) Copyright © 2016 Elsevier Ltd Terms and Conditions

5 Fig. 4 The 5-HTTLPR genotype is associated with elevated TXB2 levels in patients over 64years. Patients (a) <64years and (b) ≥64years with elevated serum TXB2 levels (TX>2.2ng/ml in blue) by 5-HTTLPR genotype. Numbers of patients on the y-axis and genotype on the x-axis.

6 Fig. 5 The 5-HTTLPR genotype is not associated with an increased level of arachidonic acid-induced platelet aggregation. Increased AA aggregation by 5-HTTLPR genotype (AA aggregation >20% in blue).
