Platelet specific collagen receptor glycoprotein VI gene variants affect recurrent pregnancy loss

This study observed increased risk for fetal losses with variants of platelet-specific collagen receptor glycoprotein VI. In silico analysis revealed the influence of glycoprotein VI in biologic pathways, collagen binding, and gene-gene interactions.

To determine whether platelet-specific collagen receptor glycoprotein VI (GP6) gene variants are associated with recurrent miscarriages (RM).


Genetic association study.


Tertiary care referral hospital.


A total of 200 women with at least three unexplained spontaneous abortions before 20 weeks of gestation and 300 healthy parous women.


Determination of variants of GP6 single-nucleotide polymorphisms (SNPs) namely; rs1671153, rs1654410, rs1654419, and rs1613662 was based on polymerase chain reaction–restriction fragment-length polymorphism.

Main Outcome Measure(s):

Genotypes and haplotypes frequencies were compared in RM case subjects versus control subjects.


We observed significantly higher occurrence of rare alleles of SNPs in GP6, namely, rs1671153, rs1654410, rs1654419, and rs1613662, among RM cases, revealing risk association for fetal losses. The synergistic effects of haplotype combinations were also evaluated and showed that four haplotypes G-T-G-G, T-C-A-A, G-C-G-A, and G-T-A-A were more prevalent among RM cases, revealing increased risk for fetal losses. In silico analysis revealed that GP6 has an impact on biologic pathways and significant influence in collagen binding. Gene-gene interaction network analysis revealed that GP6 consisted of a total of 25 interactions with 13 genes in the human genome.


These results suggest that variants of GP6 SNPs, namely, rs1671153, rs1654410, rs1654419, and rs1613662, may be associated with risk of recurrent miscarriage. In silico analyses demonstrated the influence of GP6 in biologic pathways, molecular function, including collagen binding, and gene-gene interaction in the human genome.
