Genetic association analysis highlights new loci that modulate hematological trait variation in Caucasians and African Americans

AssociationN=30,551Ken Sin Lo et al.(2011)· Human Genetics

Genetic association study in 23,439 Caucasians and 7,112 African Americans identified novel loci modulating hematological traits. G6PD rs1050828 (Val68Met) shows strong association with red blood cell count, hemoglobin, hematocrit, and mean corpuscular volume in African Americans (P < 2.0 × 10^−13), while TPM4 rs8109288 associates with platelet count in both Caucasians and African Americans (P = 3.0 × 10^−7). HBA2-HBA1 rs1211375 associates with red blood cell traits specifically in African Americans (P < 7 × 10^−8). Study replicated 36 previously reported associations and highlights ethnic differences in genetic architecture of blood traits.

About TPM1

This gene is a member of the tropomyosin family of highly conserved, widely distributed actin-binding proteins involved in the contractile system of striated and smooth muscles and the cytoskeleton of non-muscle cells. Tropomyosin is composed of two alpha-helical chains arranged as a coiled-coil. It is polymerized end to end along the two grooves of actin filaments and provides stability to the filaments. The encoded protein is one type of alpha helical chain that forms the predominant tropomyosin of striated muscle, where it also functions in association with the troponin complex to regulate the calcium-dependent interaction of actin and myosin during muscle contraction. In smooth muscle and non-muscle cells, alternatively spliced transcript variants encoding a range of isoforms have been described. Mutations in this gene are associated with type 3 familial hypertrophic cardiomyopathy and dilated cardiomyopathy 1Y. [provided by RefSeq, Jun 2022]
