Abstract excerpt
We report a case of Glanzmann thrombasthenia in a Pakistani child whose platelets express less than 10% of the normal amount of alphaIIb beta3 on their surface. Single-stranded conformation polymorphism analysis of the exons of the patient's alphaIIb and beta3 genes showed an abnormality in exon...
