Molecular diversity of Glanzmann thrombasthenia in southern India: new insights into mRNA splicing and structure-function correlations of alphaIIbbeta3 integrin (ITGA2B, ITGB3).

The molecular basis of Glanzmann thrombasthenia (GT) was studied in 40 families from southern India. Of 23 identified mutations (13 in the alphaIIb (ITGA2B) gene and 10 in the beta3 (ITGB3) gene), 20 were novel and three were described previously. Three mutations in the beta3 gene-p.
