OBJECTIVE: To evaluate the GP6 gene polymorphism in patients with sticky platelet syndrome (SPS) and fetal loss.
DESIGN: Genetic association study.
SETTING: Perinatal center.
PATIENT(S): Twenty-seven patients with SPS, manifested as fetal loss, and 42 control subjects without SPS and no history of fetal loss and thrombosis.
INTERVENTION(S): SPS was diagnosed by platelet aggregometry (PACKS-4 aggregometer; Helena Laboratories). Seven single-nucleotide polymorphisms (SNPs) of the GP6 gene were evaluated.
MAIN OUTCOME MEASURE(S): Occurrence of SNPs of the GP6 gene in SPS patients versus control subjects.
RESULT(S): We found a higher occurrence of three SNPs of the GP6 gene in SPS patients versus control subjects (rs1671153: 0.204 vs. 0.048, odds ratio [OR] 5.116, 95% confidence interval [CI] 1.536-17.03; rs1654419: 0.204 vs. 0.071, OR 3.326, 95% CI 1.149-9.619; rs1613662: 0.204 vs. 0.071, OR 3.326, 95% CI 1.149-9.619). The haplotype analysis showed a significantly higher occurrence of two haplotypes (CTGAG in haplotype 5: 0.185 vs. 0.059, OR 3.568, 95% CI 1.142-11.14; and CGATAG in haplotype 6: 0.204 vs. 0.048, OR 4.961, 95% CI 1.488-16.53).
CONCLUSION(S): Our results, especially the higher occurrence of haplotypes CTGAG and CGATAG in SPS patients, support the idea that GP6 gene polymorphism may be associated with platelet hyperaggregability, a possible cause of fetal loss.
