HGNC symbol
ITGA2 
Aliases
BR; GPIa; CD49B; HPA-5; VLA-2; VLAA2 
Common name
integrin subunit alpha 2 
Description
This gene encodes the alpha subunit of a transmembrane receptor for collagens and related proteins. The encoded protein forms a heterodimer with a beta subunit and mediates the adhesion of platelets and other cell types to the extracellular matrix. Loss of the encoded protein is associated with bleeding disorder platelet-type 9. Antibodies against this protein are found in several immune disorders, including neonatal alloimmune thrombocytopenia. This gene is located adjacent to a related alpha subunit gene. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2012]

Study Design
GPIa C807T SNP was examined in 2689 healthy Caucasians aged 17-39 years (n = 979; 505 males and 474 females), 40-59 years (n = 900; 526 males and 374 females), and 60-85 years (n = 810; 530 males and 280 females)
Conclusions
No statistically significant decrease in genotype or allele frequency was observed
