title: PEAR1 gene polymorphism in a Chinese pedigree with pulmonary thromboembolism.
abstract: To explore the correlation between platelet endothelial aggregation receptor-1 (PEAR1) genetic polymorphism and pulmonary thromboembolism (PTE).Variant loci of the PEAR1 gene were screened in a PTE pedigree, followed by verification using Sanger sequencing. These polymorphic loci were validated in 101 PTE patients and 132 matched normal patients using MassARRAY single nucleotide polymorphism (SNP) genotyping methods. The frequency differences between the allele and genotypes were compared using the Hardy-Weinberg equilibrium test and Chi-square test. The correlation between the PEAR1 gene SNP and PTE was analyzed by comparing the between-group variance differences using the χ test.Three SNPs were identified in the PTE pedigree. There was a heterozygous transition of T>C in rs1952294, and a transition of C>T in rs778026543 in 2 members in the pedigree; however, the rs778026543 was not identified in the 101 PTE patients and 132 healthy controls. The genotype and allele frequencies of rs822442 did not differ significantly between PTE patients and healthy controls (P > 0.05). The variance difference at rs778026543 between pedigree members and healthy controls was significant (P < 0.001), supporting its potential heredity.The PEAR1 polymorphism, rs778026543, but not rs1952294 and rs822442, may be a susceptibility SNP for PTE.
