Identification of a specific intronic PEAR1 gene variant associated with greater platelet aggregability and protein expression.

ABSTRACT: Genetic variation is thought to contribute to variability in platelet function; however, the specific variants and mechanisms that contribute to altered platelet function are poorly defined. With the use of a combination of fine mapping and sequencing of the platelet endothelial aggregation receptor 1 (PEAR1) gene we identified a common variant (rs12041331) in intron 1 that accounts for ≤ 15% of total phenotypic variation in platelet function. Association findings were robust in 1241 persons of European ancestry (P = 2.22 × 10⁻⁸) and were replicated down to the variant and nucleotide level in 835 persons of African ancestry (P = 2.31 × 10⁻²⁷) and in an independent sample of 2755 persons of European descent (P = 1.64 × 10⁻⁵). Sequencing confirmed that variation at rs12041331 accounted most
